Scotland have been boosted with Arsenal's Kieran Tierney starting in their clash against England at Wembley tonight.
The Arsenal defender, a key player for the national side, missed the 2-0 defeat by Czech Republic at Hampden Park in the Group D opener with a niggle.
Clarke was under pressure to start Che Adams against England following criticism of his team selection in the disappointing defeat at Hampden Park, and the Southampton forward starts here.
