England U21 boss Stuart Pearce feels Chelsea striker Danny Sturridge is about to explode.
Sturridge has drawn a blank in the first two games of the tournament.
But Pearce insists: "He's unloaded a thunderbolt in the first half which hit the bar. I was pleased with his contribution.
"Against Spain, I thought he could've done slightly better for us. I thought him and [Phil] Jones put a sterling performance in. One or players have given me a great deal to think about.
"The players who have not contributed so far might give us a lift on Sunday."
