Aston Villa boss Martin O'Neill hopes John Carew has found his "spiritual home" at Villa Park.
He told Villa's website: "John has been exceptional at Villa. His reputation seems to suggest that he doesn't spend a lot of time at individual clubs. He seems to have been floating around all over Europe.
"I hope he has now found his spiritual home here. He is very popular with the crowd and with the players. And if he continues to play like he has since he joined, he will be an incredible asset for us.
"He has to keep believing in his own ability. He has to realise he is a quality striker and he can do so much for us.
"I have been delighted with him - really pleased. John has been terrific."
