The 43-year-old has insisted that the Belgian forward can achieve anything he wants after displaying excellent form for a resurgent Aston Villa side in recent weeks
The former Genk man initially struggled to adapt to life in the Premier League after moving to Villa Park in a deadline-day switch back in August.

Former Norwich boss Lambert has been quick to praise the impact Benteke has had on his improving side, and believes the 22-year-old can only get better.
He told BBC West Midlands: "I don't want too much pressure on him but he has the potential to be one of the best.
"The potential for someone as young as that is frightening. He can be anything he wants."
Lambert believes Benteke's assist for Andreas Wiemann's goal was the most impressive aspect of his performance against Liverpool, and was delighted with the calibre of the strikes netted by his side at Anfield.
He added: "That was a world-class goal. The whole move, the backheel and Andi's finish was fantastic.
"The goals were outstanding, worthy of winning any game, especially the second."
