5 players who have disappointed so far this season

3. Krzysztof Piatek - AC Milan

Piatek's performances do not match his potential

Where did it all go so wrong for AC Milan? A club whose name is etched in the history of football, the Italian club currently sit 14th in Serie A. They have already sacked manager Marco Giampaolo, replacing him with Stefano Pioli who now has the tough task of getting this club back on track.

One of the main reasons the Italian giants are struggling this season has been due to the form of their main striker, Krzysztof Piatek. Signed in January for £30m, the striker had a brilliant start to life at the San Siro, as he netted six goals in his first five games for the club. The player was signed as a long term replacement for Gonzalo Higuain, and the initial signs were hopeful. However, the Polish forward has had a major dip in form, scoring only three goals in 12 appearances while not looking confident in front of goal.

Due to his sudden inability to find the back of the net, AC Milan are suffering. Piatek is only 24, and the club will be hopeful their main man is back to his best soon, but there is no question that he has majorly disappointed this season.
