"Split loyalties" have been reported on a 14-seater minibus carrying Aston Villa captain John McGinn's family and friends down to Birmingham, where his team plays Celtic later.
It's well known that proud Scot McGinn is a Celtic fan, and his brother Stephen said there were a few "poker faces" on the way down to the Midlands.
Villa are still in with a chance of making the top eight in the UEFA Champions League and qualifying automatically for the last 16 without having to go through the play-offs.
Speaking to BBC WM as the minibus took a pit stop at Gretna services, Stephen said the minibus had a "bit of a mix" on board.
