John Carew has admitted his switch from Lyon to Aston Villa could be 'the last big move of my career' as he prepares to make his debut in Wednesday's Premiership clash at Newcastle United.
And the former Valencia striker is convinced Villa manager Martin O'Neill can make him an even better player during his three and a half years with the midlands club.
Carew, 27, is expected to line-up alongside another Villa newcomer in £9.65million capture Ashley Young at St James' Park.
The Norwegian, who came to Villa in a swap deal with Milan Baros, said: 'I can always get better and improve - and I feel I do that every year. I am 27 now - not a teenager - but I still think I have more to offer.
'Before I think about my long-term future and what I can achieve at Villa, I will try to do the best I can on the pitch. But this could be the last big move I make in my career, so I want to make the most of it.
'The club wants to be among the very best in a few years and I would be happy to take them there.'
Carew added: 'I honestly believe that Martin O'Neill can bring even more out of me. He has been following my career for a long time and he is a great man.
'I'm already tall but he makes me feel 10 feet tall! Anywhere you go, it is important that the manager wants you.'
O'Neill is continuing to look for further signings before the transfer window closes on Wednesday, although hopes of taking Alan Smith on loan from Manchester United are understood to be fading.
But defender Jlloyd Samuel could be on the move, with Bolton believed to be expressing an interest in the former England Under-21 international.
