Krzysztof Piątek

Piątek made his debut for Milan on 26 January, in a goalless home draw against Napoli, as a 71st-minute substitute for Patrick Cutrone.

Three days later against the same opponents also at San Siro, he scored both goals in a 2–0 win in the Coppa Italia quarter-finals, and was given a standing ovation when he made way for Cutrone.

On 3 February, Piątek scored his first league goal away to Roma, which ended 1–1.

On 30 September, Piątek scored a brace inside three minutes in a 2–1 win over Frosinone to make it 8 goals in six matches, the best start to a season by a debutant since Karl Aage Hansen in the 1949–50 campaign.

In his very next match, he became the first player since Gabriel Batistuta in the 1994–95 season to score in each of his first seven Serie A appearances when he netted in a 3–1 defeat to Parma.

Krzysztof Piątek (born 1 July 1995) is a Polish professional footballer who plays as a striker for Turkish Süper Lig club İstanbul Başakşehir and the Poland national team.

Piątek began his professional career with Ekstraklasa club Zagłębie Lubin.

The following week, he scored his first brace of the season in a 5–3 loss to Sassuolo, which was followed by another strike in a 4–1 loss to Lazio, thus becoming the first player since Andriy Shevchenko in 1999 to score five goals in his first four Serie A appearances.

Piątek began his career with local side Niemczanka Niemcza and Dziewiątka Dzierżoniów (2006–2011).

During his following match, a 2–0 victory over Chievo, he scored his 10th goal across all competitions and in the process became the first player across Europe's major leagues to reach the milestone for the season.

He then moved to Lechia Dzierżoniów of III liga in 2011.

Piątek signed for Zagłębie Lubin in 2013 and initially played in junior and reserve teams of the club.

He then scored three goals in the next two consecutive matches: one against Cagliari Calcio and two against Atalanta, becoming the first Milan player to score in his first three starts in the league since Mario Balotelli in 2013.

After the arrival of Piotr Stokowiec as the new coach, however, he was quickly promoted to the first team on 14 May 2014 and then made his Ekstraklasa debut on 18 May 2014 in a match against Cracovia.

After earning promotion with the club, Piątek scored his first league goal on 14 August 2015 in a 2–1 win against Lech Poznań and helped the team finish third in the 2015–16 Ekstraklasa season, earning a medal and qualifying for European competitions for the first time in club's history since the championship winning team of 2006–07.

He played a total number of 85 matches for Zagłębie and scored 18 times, including appearances in the Polish Cup and UEFA Europa League qualifying stages.

Over the course of four seasons, he scored 15 goals in 72 appearances for the team, before joining Cracovia in 2016, for whom he scored 32 goals across two seasons.

In 2016, Piątek joined fellow Polish side Cracovia and over the course of the next two seasons, he scored 32 league goals in 65 appearances for the club.

That tally included a haul of 21 goals during his second season which saw him end the 2017–18 Ekstraklasa

campaign as the third top goalscorer in Poland.

In 2018, Piątek signed for Genoa in Italy's Serie A.

On 8 June 2018, Piątek signed a four-year contract with Italian club Genoa for a reported fee of €4 million.

He scored four goals, including a hat-trick in the opening 19 minutes, on debut in a 4–0 Coppa Italia win over Lecce.

He made his Serie A debut on 26 August, scoring in the opening six minutes of the match in a 2–1 win over Empoli.

After 19 goals in 21 competitive games in his first half-season, he transferred to AC Milan in January 2019, before signing for Hertha BSC a year later.

On 23 January 2019, AC Milan announced the signing of Piątek on a contract lasting until 30 June 2023, for a reported fee of €35 million.

He was signed as a replacement for Gonzalo Higuaín, who joined Chelsea, and he was assigned the number 19 shirt, previously worn by Leonardo Bonucci.

Ahead of the 2019–20 Serie A season, Piątek switched to the number 9 shirt.

He scored four league goals in the first half of the season before leaving the club.

In January 2020, Hertha BSC announced the signing of Piątek for a reported fee of €27 million, on a long-term contract.
