Charlie Adam has warned his Scotland teammates that Wales will have more threats to pose to them on Friday evening than just Gareth Bale.

During the previous meeting between the two British rivals back in October of last year, Bale scored both goals as Wales ran out 2-1 victors.

However, Adam has insisted that the Welsh also have other players that are capable of causing his nation damage.

"He's one of the best in the world at the moment. But they've got other good players as well. He's a big threat for them," Adam told reporters. "If he has an off night, it doesn't mean it's going to be an easy game. They're not a one-man team."

Bale is expected to shake off an ankle injury to feature at Hampden Park.
