Club career
Early career
The Čolak family immigrated to Germany in 1992 to avoid the war in the former Yugoslavia, where Antonio was born on 17 September 1993. Born in Ludwigsburg, in 2000 he signed for Stuttgarter Kickers, where he remained for eight years before returning to Freiburg in 2008. From there he joined the youth academy at Hoffenheim in 2010 for just one year, and in 2011 moved to Karlsruhe, where he made his professional debut in the lower leagues. In 2012 he was signed by 1. FC Nürnberg, initially for the reserve team. Čolak made his debut on 19 October 2013 in a Bundesliga game against Eintracht Frankfurt. He entered the field after 78 minutes for Tomáš Pekhart. He stayed in Nuremberg until 2015, playing in seven games, while for one season he was loaned out to Lechia Gdańsk, where he scored ten goals in 31 games, also contributing two assists.[citation needed]
Hoffenheim and loan spells
In the summer of 2015 he signed a contract with TSG 1899 Hoffenheim, but he did not play with the club throughout his contract. Initially he joined 1. FC Kaiserslautern on a season-long loan. On 25 July 2016, Čolak joined Darmstadt 98 on a season-long loan.[3] For the following season he was again sent out on loan, to 2. Bundesliga side FC Ingolstadt.[4]
Rijeka
Following the mutually agreed termination of the loan at Ingolstadt, in January 2018, Čolak was loaned to HNK Rijeka in Croatia until June 2019.[5] Following the end of the loan, on 22 June 2019 Čolak officially joined HNK Rijeka on a three-year contract.[6] In the 2019–20 season, he was the top scorer in the Croatian championship with 20 goals, while with Rijeka he also won two Croatian Cups. His performances also saw him win a place in the Croatia national football team.
PAOK and loan to Malmö
On 20 September 2020, PAOK agreed terms with Rijeka for the purchase of Čolak. The Greek club paid a fee over €3,000,000, while Čolak signed a four-year contract worth €450,000 per year.[7]
On 6 March 2021, Čolak moved to Swedish side Malmö FF, on a loan deal until December 2021.[8] At Malmö FF, Čolak quickly established himself as a prolific goalscorer with ten goals in his first 15 appearances and went on to win the title with Malmö. In December 2021, with Malmö FF unwilling to pay the buy out of €3 million that had been set in his loan contract, Croatian newspaper "Sportske Novosti" linked Čolak with a move to Dinamo Zagreb. He returned to PAOK from the beginning of January 2022.[9]
On 20 March 2022, he scored a goal after an Alexandru Mitriță assist, helping PAOK to gain a 1–0 away win against rivals AEK Athens for the Play-off round. It was his first goal for the club after his return from Malmö FF.[10]
