Arsenal midfielder Mathieu Flamini will sign for Italian giants AC Milan, according to the Serie A club's vice-president. Adriano Galliani revealed after his team's 2-1 triumph over Inter in today's Milan derby that the Rossoneri are close to sealing a deal for the Frenchman whose contract with the Gunners expires at the end of the season. Galliani said: 'Flamini will arrive tonight in Milan and will sign a four-year contract.' The 24-year-old is expected to undergo a medical tomorrow.Gunners boss Arsene Wenger had admitted after today's 1-0 victory over Everton that he was not 'super-confident' Flamini would still be at Arsenal next season. Despite the offer of a lucrative new five-year deal - understood to be worth around £55,000-a-week - from the Barclays Premier League club, his future remains unresolved. Both AC Milan and Juventus were reported to be tracking the France international, who formed a fine partnership with Cesc Fabregas at the heart of the Arsenal team this season having looked to be on his way out of the club at the end of the last campaign. It is understood Flamini said his goodbyes to some staff as he left the car park after today's match at the Emirates Stadium. 'Frankly, I don't know,' said the Arsenal manager when asked about Flamini's future. 'But if you ask me was I overall super-confident, I would say no. 'He has an offer on the table which is valid until tomorrow, then we will see. 'I am not confident, but also not worried. The situation is not in my hands. 'We have done what we had to do, it is now down to him to make a decision.' Wenger called for the matter to be resolved expediently one way or another. 'At some stage you have to make a decision and if he goes we have to look at our options,' said the Arsenal boss. 'We can't wait until July. You could lose players if they come on the market. ``My ideal solution is that he stays, so I am not happy if he goes - but we've done everything we can.'
