England stars Mason Mount and Ben Chilwell are forced to self isolate after hugging Billy Gilmour

England stars Mason Mount and Ben Chilwell have been forced to self-isolate after they were spotted hugging Covid-positive Scotland star Billy Gilmour at Wembley.

The trio, who are all teammates at Chelsea, were pictured embracing at the end of Saturday’s Euro 2020 clash.

The Scotland FA announced earlier that Billy Gilmour must quarantine for 10 days after testing positive for Covid following the draw against England on Friday night.

And now the England pair have been told to self-isolate, which could prevent them from participating in tomorrow’s final group game versus Czech Republic.

They could also be forced to miss the start of the knockout stages which start next week, while Public Health England have been in contact with the FA over the issue. 

It comes as it emerged that England’s footballers won’t receive extra coronavirus tests despite Gilmour testing positive for Covid-19 just three days after facing them at the Euro 2020 championships.

The 20-year-old Chelsea footballer will now be forced to self-isolate for ten days, hours after playing a major role in Scotland’s goalless draw with England at Wembley Stadium last Friday in his first start for the national team. 

All 26 England players and the support team returned negative results after the latest round of PCR testing by Uefa yesterday – and the full squad trained at Spurs Lodge in Chigwell today. 

But they have received no further tests because they were not deemed ‘close contacts’, despite being in close proximity to Scotland’s stars at the match. 

No other Scotland players have been affected or identified as close contacts, meaning all will be available as they face Croatia in a winner-takes-all Group D clash at Hampden Park in Glasgow, which is also tomorrow at 8pm.  

All Scotland’s other 25 players tested negative for Covid-19 after lateral flow tests following training today, but the lack of players being defined as ‘close contacts’ or extra testing for England provoked outrage on Twitter today.

Twitter user Stuart Graham said: ‘So I’m really confused, if a pupil in my daughters class ‘bubble’ tests positive for Covid then the whole class will isolate, yet Billy Gilmour tests positive yet Scottish team don’t have to self-isolate.’

Another tweeted: ‘I’m honestly baffled with this Covid-19 nonsense, how can they say no one is considered as a close contact to Billy Gilmour when all the players shared the same dressing room etc – totally f***ed up.’

And a third added: ‘So Billy Gilmour has to isolate but the entire team, whom he has been in very close contact with, don’t. Yeah, right, that makes perfect sense. If a kid in class tests positive the whole class are sent home. Get an effin grip. It’s all utter nonsense.’

The Scottish and English football associations remained in talks with Public Health England this morning regarding close contacts of Gilmour, but none have been identified. 

An SFA spokesman said: ‘The Scottish FA can confirm that a member of the Scotland national team playing squad, Billy Gilmour, has tested positive for Covid-19.

‘Having liaised with Public Health England since the positive test was recorded, Billy will now self-isolate for 10 days and therefore miss tomorrow’s Uefa Euro 2020 Group D match against Croatia at Hampden.’

Gilmour will play no part in tomorrow’s match for Scotland, who are in their first major tournament since World Cup 1998. They sit bottom of Group D with one point and need to beat Croatia to have a chance of progression. 

Scotland have not yet confirmed if Gilmour has received his Covid-19 jabs, but this is viewed as unlikely due to his young age and involvement in elite sport which would mean he may not want to risk getting any side effects. 

Half a dozen other teams in the tournament, which has been delayed by a year, have also suffered Covid-19 cases – and Gilmour’s positive test is the second to hit the Scotland camp since the squad met up earlier this month.  

All Euro 2020 teams are living in a bubble and avoiding all contact with the public for the duration of their involvement in the tournament. Players are having regular PCR tests – with everyone getting tested 48 hours before every match as per UEFA regulations – and their temperatures are taken when they arrive at stadiums.  

Any player, coach or official who returns a positive result is immediately removed from the group and quarantined, followed by universal testing of the entire squad and any known contacts. 

Opposition players are not deemed close contacts unless they spend an extended period of time with the positive player.

Guidance from England’s FA states match play is not considered ‘close contact’ so no action is needed unless individuals experience symptoms, in which case they must self-isolate from that point as per Government guidance. 

Sheffield United midfielder John Fleck sat out both of the Scots’ warm-up fixtures against Holland and Luxembourg after contracting the virus, and another six players missed the 2-2 draw with the Dutch as a precaution, although they were not formally designated close contacts of Fleck.

Soon after news broke of Gilmour’s positive test at about 10.30am this morning, a video surfaced from the team hotel where the young midfielder was seen enjoying playing ping pong.

Taken on Andy Robertson’s Instagram story, the video shows Gilmour, along with John McGinn, unwinding with a game in the team hotel. The video has since been deleted from the Liverpool full-back’s Instagram account.

Sportsmail has learned that there are no close contacts in the Scotland camp that will be forced into isolation as a result of the positive test.

Gilmour was left out of the side for the opening group defeat to Czech Republic but proved a revelation in the match at Wembley against England.

Both Scotland and England players are routinely tested for Covid-19 and the task now will be to determine if Gilmour is merely an isolated case of a positive result.

The Blues youngster was hailed by Patrick Vieira, Graeme Souness and Gary Neville as a difference maker in 76 minutes at Wembley in what was his first start for his country.

‘I really love his technical ability. He loves to get on the ball,’ Vieira said on ITV. ‘His team-mates aren’t scared to give him the ball because they know how good he is on the ball. I think he has a really good future ahead of him.’

The youngster has been so impactful in the early part of his career that he has claimed the man-of-the-match gong on his first appearances in the Premier League, the FA Cup, the Champions League and the Euros.

Gilmour was almost certain to be the leader of the midfield on Tuesday at Hampden for the match-up against Croatia. But his enforced absence arrives as a crushing blow for Scotland and their hopes of progressing.

Even if Scotland progress without him, his 10-day isolation period would also rule him out of any last-16 tie all but ending his Euros run after one game.

Having outshone a string of Premier League players on Friday night, Gilmour was expected to start again against Croatia, with the tantalising prospect of him going head-to-head with Real Madrid midfielder Luka Modric.

But manager Steve Clarke will now need to rethink his plans. Manchester United midfielder Scott McTominay, who slotted back into a defensive role against England, is likely to be returned to his usual position protecting the back three. Clarke is due to hold a press conference today at 5.45pm.

Earlier this year, experts told the Sunday Times in March that there had not been a single instance of on-field transmission of Covid-19 in UK football, rugby union, rugby league or American football.

Professor James Calder, the independent chairman of the government’s committee on the return of elite sport, said all instances of Covid-19 being transmitted within football had happened away from the pitch.

He said at the time: ‘We have not had any cases of transmission on the pitch in football. It is what happens off the pitch, in the changing rooms, car-sharing, [not] social distancing that appears to be the risk.

‘There was concern contact sports such as rugby could have very different problems compared to football and cricket but those sports have done very good work to identify the risks on the field.’

A Premier League study last year showed players would be within the infection distance of two metres, if one player on the pitch had the virus, for an average of just 39 seconds during a match.
