Bayern Munich reportedly eyes Porto winger Oskar Pietuszewski as Luis Díaz backup

Bayern's interest in the Porto winger

German media report that Bayern Munich is tracking Oskar Pietuszewski, the 18-year-old Polish international who plays for FC Porto. Bild journalists Christian Falk and Julian Agardi named him on the Bayern Insider podcast as an option for the left side of the attack. Florian Plettenberg of Sky Sport, cited by Polsat Sport, said the club's scouts rate his potential highly, and sporting director Max Eberl is described as a strong admirer. Bayern's scouts first watched him in late 2025, during a Conference League match against Rayo Vallecano, but he chose Porto's offer at the time. According to N-tv's transfer update, the club now has him high on its list for the coming summer.

Luis Díaz's injury and the left flank

The search follows an injury to Luis Díaz, the Colombian winger who is out with a long-term problem according to SAPO. Interia reports that Díaz is 29, joined Bayern from Liverpool in summer 2025, and has scored five goals and provided one assist in 11 games this season. In his absence, coach Vincent Kompany has used Alphonso Davies on the left wing, a stopgap the club wants to replace through the transfer market, according to Bild. Focus, citing Bild, lists three targets: Rio Ngumoha of Liverpool, Pietuszewski, and Junior Kroupi of AFC Bournemouth. Ngumoha is described as the first choice, with a contract at Liverpool running to 2028 and a market value of about 50 million euros. Focus adds that Bayern instead signed Ismael Saibari as another attacking option.

Contract, price and recent form

N-tv reports that Pietuszewski joined Porto from Jagiellonia Białystok in January 2026 for about 8 million euros. His original contract ran to 2029, but he extended it early at the end of May to 30 June 2031. N-tv, citing exclusive Sky information, puts his release clause at 60 million euros, while Polsat Sport says he is currently valued at around 25 million euros, so the two figures stand apart. In 22 matches for Porto he has four goals and four assists. Injuries have disrupted his first full season in Porto's colours, but he has recovered and was on the bench for the Champions League match against Napoli, which Interia says Porto won 4-1. Bayern also requested accreditation for that match, according to SAPO.

What is still open

N-tv reports that no concrete negotiations or formal offer from Bayern exist so far, and it is still unclear whether the club would be willing to pay the clause. Bayern is expected to focus on the position in the summer, while keeping winter options open, according to N-tv's transfer update. Earlier, when the German club was linked to him, his agent Mariusz Piekarski denied any formal proposal to Jagiellonia Białystok, SAPO reports. Interia notes that Díaz could leave Bayern after the season. A decision on any approach has not yet been made.
