Milan clinch Flamini signature May 06 2008
Arsenal manager Arsene Wenger must plan for life next season without French midfielder Mathieu Flamini.
The 24-year-old completed his move to AC Milan on Monday, agreeing a four-year contract with the Italian giants.
Flamini, out of contract at the Emirates Stadium in the summer, underwent a medical and has reached an agreement over personal terms.
Milan vice-president Adriano Galliani revealed the signing was imminent after his team's 2-1 triumph over city rivals Internazionale in Sunday's derby.
Wenger admitted on the same day that he was not "super-confident" the France international would still be at Ashburton Grove next term.
The player put in a fine performance at the San Siro as Wenger's charges knocked the Rossoneri out of the UEFA Champions League at the last-16 stage in March.
Flamini will compete for a place in Milan's midfield alongside Brazilian Kaka and Italy trio Gennaro Gattuso, Andrea Pirlo and Massimo Ambrosini.
Carlo Ancelotti's men climbed into the final qualifying place for the UEFA Champions League on Sunday, leapfrogging Fiorentina who lost 2-1 at Cagliari.
Flamini's last match as a Gunner will be Sunday's Premier League trip to Sunderland, before he officially joins the Serie A outfit's ranks on July 1.
Milan sporting director Ariedo Braida said: "I have to say Flamini was a player that Ancelotti really wanted and Milan is like a family, where decisions are made jointly."
