Marc Wilmots has said that Romelu Lukaku has been putting "too much pressure on himself" to perform at the World Cup with Belgium.
The Belgian side have won both of their games so far, but the Chelsea striker is yet to feature on the scoresheet.
The coach told FIFA.com: "He puts too much pressure on himself. I messed up in my first two World Cups because I was obsessed with winning.
"I was expecting the younger players to handle the occasion less well, simply because they would be thinking about nothing else but the need to win."
Belgium face South Korea in their final Group H match later today.
