SCOTLAND’S qualification hopes were hit on the eve of their must-win Euro 2020 showdown with Croatia after Billy Gilmour returned a positive coronavirus test.

The Chelsea midfielder impressed in his first Scotland start on Friday as he helped the team earn a goalless draw with England at Wembley.

That result left Steve Clarke’s side still in with a shot at reaching the knockout stages.

But Scotland received a major blow ahead of facing Zlatko Dalic’s team at Hampden, with the Scottish Football Association announcing the 20-year-old Champions League winner will have to quarantine for the next 10 days.

The other 25 players in the Scotland squad trained this morning and all tested negative from precautionary lateral flow tests immediately afterwards. Gilmour tested positive after a PCR test on Sunday.

It is understood the Scotland camp are confident no players will be deemed close contacts of Gilmour when Public Health England completes its review of the situation.

The squad travelled up from their base near Darlington to Glasgow on two planes to ensure strict social distancing.

Having outshone a string of Premier League players in London 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 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.

Gilmour’s positive test is the second to hit the Scotland camp since the squad met up earlier this month.

Sheffield United midfielder John Fleck sat out both of the Scots’ warm-up fixtures against the Netherlands and Luxembourg after contracting the virus.

Another six players missed the 2-2 draw with the Dutch as a precaution, although they were not formally designated close contacts of Fleck.
