Christian Benteke is desperate to get back for Aston Villa.
Benteke, currently on international duty with Belgium, is serving a three-game domestic ban after shoving Tottenham's Ryan Mason in the face a week last Sunday.
He said: "When you come back from a long injury it's frustrating.
"I needed - not to be hard - but to be maybe a little bit more level.
"It was tough to learn that I would miss the World Cup, especially when it is your first big injury.
"Now after this little break, I know I can be stronger than before.
"I will come back and be at my old level."
