Markovic's transfer to GKS Katowice came after a difficult final season at IFK Göteborg, where he recorded two assists in 14 league matches, 12 of which were starts, according to reports. He had a contract with IFK Göteborg until the end of the 2025 season. According to Fotbollskanalen, Markovic described being excluded from training at Valhalla IP and later from the winter training camp as extreme and brutal.
The specific reasons for his exclusion remain unclear. At GKS Katowice, Markovic has started four consecutive matches, according to reports, and the club sits in third place with three rounds remaining in the Ekstraklasa, according to reports. According to Fotbollstransfers, Markovic said he feels very good and that goal production has loosened up.
He attributed his success to fitting well into the system and being in a functioning team. The terms of his transfer and his long-term future at the club are not publicly known.
