Benteke ruptured his Achilles tendon in training last Thursday and Villa manager Paul Lambert on Thursday confirmed the player has now returned to his home country for the operation.

"Our doctor (Roddy Macdonald) is over in Belgium and he has spoken with the surgeon, and it's pretty imminent he will get it done -- today, tonight or tomorrow," Lambert said.

"Then after that it's all about the rehabilitation with him. When it's a long-term injury you have good days, bad days, like everyone else when they are out injured for a long time, but he'll be fine."

Even though Benteke, 23, is out of this year's World Cup in Brazil and is unlikely to return to match action until October at the earliest, Lambert is confident he won't lose heart and will be eager to return as quickly as possible.

"It's probably just sinking in now he is going to miss the World Cup, which is a major blow for him," Lambert added.

"But he is in a generation of Belgian players who will qualify for a few more tournaments down the line.

"He is still a young guy in that group, and he will come back totally strong, given the way he is as a guy and his physical aspect.

"Of course, everybody is different as to how they want to progress, and how quick their body heals.

"But looking at Christian and the way he is as a pro he will knuckle down and work really hard to get back."
