Billy Gilmour has been through the emotional wringer in the past few days.
A Scotland debut and man-of-the-match display against England has quickly been followed by a positive COVID test which has ruled the midfielder out of the Scots' crunch tie with Croatia.
The 20-year-old finds himself in good company, however, as our Planet Sport Euro 2020 COVID XI shows.
Tim Krul (Netherlands)
The Norwich City No. 1 contracted COVID in January and admitted it "knocked him for six". However, in a strange twist, Krul became the beneficiary when Netherlands' first choice keeper Jasper Cillessen tested positive ahead of the Euros. Manager Frank de Boer opted to cut the Valencia keeper from his squad, allowing Krul to start both Netherlands' opening group games.
Leonardo Bonucci (Italy)
The central defender tested positive for coronavirus at the end of March after returning from international duty with Italy. It was a pretty ill-fated trip all in all for the 34-year-old who didn't even feature as the Italians beat Lithuania 2-0. Fully recovered, he played all three of Italy's Euro 2020 fixtures as they coasted into the last 16 without conceding a goal.
Aymeric Laporte (Spain)
Laporte tested positive, along with Manchester City team-mate Riyad Mahrez in September. A France player at the time, he is now established in the centre of defence for Spain having completed 90 minutes in both their Euro 2020 group games.
Caglar Soyuncu (Turkey)
Soyuncu tested positive for COVID while on international duty with Turkey in the spring. His time in isolation lasted longer than Turkey's involvement in Euro 2020.
Raphael Varane (France)
The Real Madrid defender tested positive for COVID-19 in April, ruling him out of the Champions League fixture with Liverpool. It was even more annoying as, with the Reds clash in mind, Varane had been rested for Real Madrid's preceding fixture. Has clocked up 131 completed passes in France's two opening games at Euro 2020, an efficiency rate of 94% - the same as the Moderna vaccine, though the Moderna vaccine has completed far fewer headers.
Billy Gilmour (Scotland)
Gilmour picked up rave reviews as Scotland stifled England on their way to a crucial point in Group D. Thankfully for the England players, his subsequent positive COVID test shouldn't be a worry - none of them got near him on Friday night.
Paul Pogba (France)
Sergio Busquets (Spain)
Busquets tested positive for COVID ahead of the Euros, the eighth Spanish international to contract the virus. Thankfully, a negative test means the Spain skipper has been able to rejoin the squad ahead of their final group game.
Xherdan Shaqiri (Switzerland)
Shaqiri was diagnosed in October after joining up with Switzerland. His absence from the Liverpool squad was barely noticed, however, as he had not even made the bench for their opening five fixtures. He only went on to make five league starts for Jurgen Klopp's side but is still a fixture for the Swiss, starting all three of their group games and scoring twice in their victory over Turkey.
Cristiano Ronaldo (Portugal)
Ronaldo was another player to return a positive test while on international duty. The veteran missed four Juventus matches while isolating, in which time the Italian giants won just once. Has already bagged three goals at this summer's Euros, although Portugal's progression out of the group is far from certain.
Kylian Mbappe (France)
Mbappe returned his positive test fresh from scoring France's winner in their Nations League clash against Sweden in September - one of seven Paris Saint-Germain players to contract the virus. Has featured in both France's opening games of Euro 2020 but has failed to find the net in seven attempts. Hopefully, his COVID shots prove more successful.
