Marc Wilmots has confessed that striker Romelu Lukaku was left feeling unhappy following his removal in Belgium's victory against Russia.

The 21-year-old, who was also withdrawn in the Red Dragons' 2-1 win over Algeria last week, was substituted before the hour mark in place of eventual goalscorer Divock Origi.

"It's not a problem," Wilmots is quoted as saying by The Independent. "That's normal. It happened to me as well. He had to go to the bench after 55 minutes. Of course, he's not happy."

Lukaku has had just two touches of the ball inside the opposition box in over 113 minutes of football during the 2014 World Cup.
