AC Milan have completed the signing of Krzysztof Piatek from Genoa on a four-and-a-half-year deal, according to Sky Sports.

The Rossoneri announced on Wednesday night that Piatek has completed his move to the Italian club on a deal that could keep him at the San Siro until June 2023. The deal will also see him earn around £34,000 per week (£1.7m per year).

The £31m deal sees Genoa lower their initial asking price of €40m, but Milan will have to pay the transfer fee upfront and include add-ons should they finish in a top four spot in the Serie A come the end of the season.

Scoring sensation Krzysztof Piatek equals an AC Milan record

Krzysztof Piatek continued his impressive form at AC Milan by becoming the first player to score in his first four starts in since 1998.

Piatek, who is expected to put on the number 19 shirt, will be presented to the media on Thursday afternoon at noon and will join his new teammates for his first training session later that afternoon.

Milan have moved for the former Cracovia striker after Gonzalo Higuain saw his loan deal with Gennaro Gattuso’s side cut short to join Chelsea on loan for the remainder of the season.

The Polish international moved to Italy last summer and has been very successful, with 19 goals scored in 21 games for Genoa so far this season.
