According to the reliable Gianluca Di Marzio, the Premier League club have already submitted an offer for the player. The bid is thought to be around €30m.
Apparently, the two clubs have already had a meeting and the Aston Villa director met with the Rossoneri directly.
It will be interesting to see how Milan react to the bid now. Piatek is unlikely to be a starter at the club following the arrival of Zlatan Ibrahimovic and it would make sense for him to move on.
Aston Villa are in desperate need of a striker and Piatek should prove to be a quality addition.
