Belgium boss Marc Wilmots admits he is pondering what to do with his strike force in his side's second Euro2016 match this weekend.

The Red Devils were humbled by the experienced Italy 2-0 in their Group E opener on Monday and one of the many that underperformed for Wilmots was Everton striker Lukaku.

Ahead of Saturday's crunch clash wth the Republic of Ireland, Wilmots is unsure if Lukaku will start in Bordeaux as he contemplates who out of Michy Batshuayu, Divock Origi, Christian Benteke or Yannick Carrasco could quite possibly replace the 23-year-old.

"He had the confidence for the World Cup, he had it now," said Wilmots.

"He has also become better at rebounding. But there are strikers who work very well in training and who might get their chance.

"Look, we have no (Graziano) Pellè, (Robert) Lewandowski or (Mario) Mandzukic.

"These are experienced attackers. We have strikers with a huge margin progression. And with different profiles.

"I see which type works best against Ireland. Not counting the person. Belgium's what counts."
