Wales boss Chris Coleman believes that Gareth Bale, Joe Allen and Aaron Ramsey have to perform to their best in their Euro 2016 qualifier against Belgium on Sunday.

Bale featured in his team's win over Cyprus last time out and has managed to overcome fitness problems to be available for the clash against Marc Wilmots's side.

Meanwhile, Allen and Ramsey are fit again to play for Wales after missing the matches against Cyprus and Bosnia-Herzegovina, and Coleman feels that they will need to produce their best display in order to guide their side to a positive result against the world's number four ranked side.

Coleman told reporters: "They have got to produce. They are all top players, but they have to produce to at least the level of what we have got from the other players who have been with us when they have been missing.

"We have got Rambo and Joe back after the last camp and of course they are top players. But they have to give us everything they have got because that is what we need.

"We have got to go there and give it a real go, without being cocky, because we have got a bit about us."

Wales are top of Group B ahead of the clash in Brussels.
