KSW champion Adrian Bartosiński accuses his former manager Artur Gwóźdź of neglecting his contracts, preventing him from joining the UFC in 2022. Gwóźdź counters with scathing remarks, calling Bartosiński "ready to eat his own shit" to join KSW. Their 2024 split marks the end of a five-year collaboration, marred by tensions over a contract linked to the show Tylko Jeden.
To remember:
- Adrian Bartosiński accuses his former manager Artur Gwóźdź of neglecting to secure a contract with the UFC in 2022.
- Gwóźdź fires back, recalling that the KSW contract was signed after the show Tylko Jeden, which was partially funded by KSW and a public crowdfunding campaign.
- Gwóźdź calls Bartosiński "ready to eat his own shit" to join KSW, marking the definitive break between the two men.
A Controversy Escalates in the World of Polish MMA
The rivalry between Adrian Bartosiński, the KSW welterweight champion, and his former manager Artur Gwóźdź has taken an explosive turn in recent days. During a live stream on Counter Strike, Bartosiński accused Gwóźdź of negligence in managing his contracts, claiming that without his intervention, he would have joined the UFC as early as 2022. This statement immediately reignited hostilities between the two men, whose relationship had already been strained since their split at the end of 2024 after five years of collaboration.
Gwóźdź was quick to respond with venom. On X (formerly Twitter), he recalled the circumstances surrounding the KSW contract signed by Bartosiński, particularly after his participation in the show Tylko Jeden, where the champion had not performed well. To fund his participation, KSW covered half the costs, Gwóźdź contributed 5,000 zł, and the rest came from a public crowdfunding campaign. An arrangement that, according to him, proves his commitment to Bartosiński.
Personal Accusations Seal a Definitive Break
The verbal escalation reached its peak when Gwóźdź called Bartosiński "ready to eat his own shit" to join KSW. A shocking statement that underscores the depth of the rift between the two men. Their once-fruitful collaboration has now turned into an open conflict, with each side trying to discredit the other.
Bartosiński, for his part, stands by his accusations, asserting that Gwóźdź failed in his role as a manager by preventing him from seizing major opportunities, such as a UFC contract. A controversy that has now moved beyond the realm of sports to touch on the professional credibility of both parties.
This affair sheds light on the contractual and managerial stakes in MMA, where the relationship between fighters and managers can spiral into public confrontation. Between alleged negligence and personal accusations, the Bartosiński vs Gwóźdź feud reminds us that the behind-the-scenes drama in combat sports can be just as intense as the fights themselves.
