The two teams meet in a Euro 2024 qualifier at Wembley on Sunday.
OâNeillâs side will look to build on Thursdayâs 2-0 victory in San Marino.
Aston Villa midfielder John McGinn scored his 16th international goal in the 21st minute and it was then mostly a dull affair until Manchester United's McTominay grabbed a second from the bench in the 87th minute before adding another from close range in stoppage time. The visitors ended the match with 10 men after Nicholas Ioannou was sent off for picking up a second yellow card after booting the ball away. It is the first time since 2006 that Scotland have won their opening European Championship qualifying game.
