Roy Keane is confident that Gareth Bale's influence is enough for Real Madrid to defeat Juventus on Wednesday night.

The Welsh winger has come under plenty of scrutiny for his recent sub-par performances which was evident in Real's 2-1 loss in the Champions League semi-final first leg in Turin last week.

Ahead of the return bout at the Santiago Bernabeu, former Manchester United captain Keane spoke of Bale and hinted that if he brings his best, Carlo Ancelotti's men will get the better of the Italian champions.

"There's no doubt in his [Bale's] talent," he said during ITV's coverage of the Bayern Munich v Barcelona match on Tuesday night.

"We've seen him do it before. We've seen him do it last year in the big, big games. If Gareth is at it tomorrow night, then they've got a chance.

"That's if he turns up. He's a top player."
