When will Milan finally buy wing-players ??

I already say this for a few years, and after the psv-game i say this again : Milan misses a true winger !! When we are playing against teams that play defense with 10 players, we miss creativity on the wings to create chances. Kaka, Seedorf, Gattuso, Pirlo : all central players! If it doesn't go through the centre, we often start to give long balls to the strikers. That's because we miss a wingplayer. Against psv we only started to get dangerous after Serginho was brought in. Milan is sometimes way too predictable : everything goes through the centre. Sure, we have Cafu and Kaladze, but they are offensive wing defenders. We need a true original, old-style wing player. Yes, someone like Roberto Donadoni was ! Remember how he created chances for us, when we were struggling to beat a smaller side ? With his speed, dribbles and crosses he was a real danger on the left side. Someone like him, we miss. The only player who can do that is Serginho, but he's too unstable. Jankulovski can do that also, but he's more defensive, more a type Kaladze.
No, we really need a left or right wing player that can create chances from the wing. Have u guys seen Farfan and Beasley for psv ? Milan-defenders had a lot of trouble with them. Why ? Because they are fast, strong and have great dribble-skills.
So 1 of those 2 players would be excellent signings i think. Chelsea for example has 3 good wingers : Robben, Wright-Phillips and Duff. Duff sits mostly on the bench.
Dutch teams mostly have good wing-players because their tactics are mostly with 3 strikers: 1 centre striker and a left and right wing. Overmars and Zenden were also that kind of players. Other good wingplayers are for example Joaquin (Betis), Wilhelmson (Anderlecht), Ze Roberto (Bayern Munich). We had Cosmin Contra, but Ancelotti used him as right back, like he uses Cafu right now. But Contra is not that strong as Cafu is in defense, but attacking he's not worse then Cafu. Contra was a good player, it's a pity Milan sold him after only 1 year.
But my point is, Milan needs at least 1 true wing-player of world class in their squad. That will help to solve the problem that Milan has, namely to create chances against smaller, defensive-orientated teams.
