Wilmots claims he has no injury concerns ahead of the opener with Italy on Monday, including former Arsenal defender Thomas Vermaelen.

Chelsea star Hazard, who is to captain his country at the European Championship, limped out of a behind-closed-doors training session on Friday after 50 minutes, sparking concerns that he could be a doubt for his side's opener with Italy in Lyon on Monday.
But Wilmots has shrugged off those concerns, telling reporters: "I don't think it [Hazard's injury] is serious, just a knock."
Former Arsenal defender Vermaelen was also considered a doubt for the Red Devils earlier this week, but his boss insists that he too will be available for selection.

He added: "Thomas has done well in training over the last days and is completely ready for the battle. He has no more problems."
Wilmots has insisted there are no other injury problems within his 23-man squad, which at a total value of nearly £319 million is the most expensive of the tournament.
Following Monday's game with the Italians, Belgium take on the Republic of Ireland on June 18th, before facing Sweden four days later.
