Steve Clarke turned quickly to plan B after Covid-19 deprived him of three key players for Scotland’s Euro 2020 play-off semi-final against Israel at Hampden Park on Thursday night.

The national team’s preparations were left in disarray after Stuart Armstrong returned a positive test for COVID-19 on Wednesday morning.

The midfielder returned a negative test on arrival at Oriam on Monday but the supplementary UEFA test returned a positive result two days later.

As well as the three international fixtures, Arsenal defender Tierney will also miss his club’s Premier League clash with Manchester City on Saturday, October 17 as his self-isolation is due to end three days later.

He said in a statement on Arsenal’s website: “I’m so disappointed and frustrated to be in this situation.

“I have adhered to all regulations and made sure I was socially distancing from my team-mates in the hotel.

“I’ve also tested negative. I know Arsenal and the SFA are now in discussions with the Scottish authorities to gain a further understanding.”
