Belgium boss Roberto Martinez is hoping for a "fearless" performance from his team in the World Cup semi final on Tuesday.

It is a tough test for Belgium, who squeezed through their quarterfinal clash against Brazil despite a difficult second half, where they had to defend for the majority of play.

Now Martinez wants the team to push on and win the tournament.

"This group has to play with no fear at all," Martinez said in an interview with ESPN.

"If we approach this match with fear within us, we will bring ourselves down and we'd be able to do so much less than what we can actually do.

"To play without fear would probably be the one thing which would help us the most."
