Belgium manager Roberto Martinez says he is wary of a Japan team with 'incredible energy' ahead of Monday's World Cup last-16 clash.
The free-scoring Belgians go in as firm favourites, taking with them a 100 per cent record from the group phase and netting nine goals in beating Panama, Tunisia and England.
With players like Eden Hazard and Romelu Lukaku at his disposal, Martinez's team have more than enough quality to match their achievement at the last World Cup and secure a place in the quarter-finals, where Brazil could await them.

Most pundits are predicting a comfortable Belgium win, but Martinez has short shrift for such a theory.
'They are footballers with an incredible energy and a great capacity to get really high up the pitch very quickly,' he said. 'This Japan team shows a lot of good experience, a lot of players who have played in big leagues in Europe for a long time. They know what it takes to win a game of this calibre.
'This is a group of players that know what they are doing. I expect a very difficult game.
'They are capable of creating problems due to the dynamic approach that they have.'
