No, he hasn`t(not that I know of at least). I know Newcastle wants him, but they`ve rejected any offer so far. However even if he is one of those up-and-coming stars I think Villa has a fair chance if our interest is serious. We have a name and a seriously improving technical organisation with a lot of potential within not too many years. K-J Huntelaar isn`t too old, and has still some things to learn, and it would be better for him to play in a sub top club where he`s going to get playing time rather than being benched on Chelsea or United.
Ajax has also become one of the biggest has-beens in European top football with a chronic problem of bad organising and their fans are very unhappy with their performance, and it`s a badly hidden secret that Ajax-players are among the most frustrated football players that exist, mostly due to their lack of being result oriented.
Now I might reveal that I`m also a PSV-fan, and I`d be super happy to see any key player being ripped off their squad...;-)
