Arsene Wenger is determined to end any lingering doubts over Thierry Henry's future by resolving talks on the Frenchman's new contract as soon as possible.Henry revealed his desire to stay at the club last weekend, giving Arsenal a huge lift after interest from Barcelona in luring the striker to the Nou Camp. Arsenal nevertheless still need to reassure Henry over their ambitions in the transfer market, as well as finding a deal over his wages. Wenger declared: 'I always felt that, once he had made his mind up, the situation should be sorted out quite quickly. 'That's my desire now because, the longer it lasts, it is not good for the club and for the team. 'If he did not make his mind up, I was ready to wait. But now he has made his mind up, I feel we have to act quickly. 'That, again, doesn't depend only on me - it depends on the negotiations and when he will be ready to sign. But I think the quicker, the better.' Henry is likely to want certain assurances from Arsenal over moves to strengthen their squad, both in the January transfer window and at the end of this season. Wenger, meanwhile, is also looking to resolve the futures of Jens Lehmann and Robert Pires, who are both out of contract at the end of this season. The Arsenal boss told Sky Sports News: 'Jens should be sorted out in January. We've played so many games and I don't find the time to talk to players at the moment. 'We'll have a chat with him and Robert - not this week, as we play twice, but next week.'
