The 20-year-old's name has attracted attention following an impressive start to the season, but claims of a potential move to Spain have been disputed by journalists familiar with the situation.
The speculation even reached the Poland squad, where Matty Cash jokingly called out “Mourinho!” and “Real Madrid!” during a training session when addressing Reguła. The exchange was intended as a joke between teammates, but it reflected the attention surrounding the youngster.
Reguła has scored five goals in 14 Ekstraklasa appearances, including a recent double against Lech Poznań. His performances have helped establish him as one of the emerging talents in Polish football, and he made his senior international debut in October.
The initial reports originated in Germany, with claims that Real Madrid were monitoring the attacking midfielder and that Mourinho had followed his development during his time at Benfica.
However, the suggestion that the Spanish club were preparing to move for him has been strongly questioned.
Polish journalist Tomasz Włodarczyk, speaking through Meczyki, dismissed the Real Madrid story, saying: “According to a quick verification, it's nonsense. There is no such thing.”
He also suggested that Borussia Dortmund remained a more realistic destination should Reguła leave Poland. The German club had reportedly come close to signing him during the previous summer transfer window, before pursuing Ethan Nwaneri instead.
Polish outlet Polskie Radio also reported that there had been no negotiations between Real Madrid and Zagłębie Lubin, despite the speculation surrounding Mourinho's alleged interest.
Reguła's development has nevertheless attracted attention beyond Poland. His performances, versatility and ability to contribute goals from an advanced midfield position have made him an increasingly prominent name in the transfer market.
He is contracted to Zagłębie until 2028, meaning any potential move would require negotiations with the Polish club.
For now, the Real Madrid link remains unsubstantiated. Reguła's growing reputation is genuine, but there is no confirmed agreement or evidence of formal talks with the Spanish giants.
