Lewandowski is already one of the most rumoured players these days. This must be about the gossips about him to leave even in the transfer window last summer. He still has a contract with Bayern Munich running until the summer of 2023 now. It is still early to talk about a probable transfer for him this summer. But if he doesn't extend his contract until that time, then I will start believing that he would leave the team before the next season. But his next station may not be Real Madrid if they sign Haaland.
Lewandoskii is a star player, and people are curious to know if he will extend his contract with Bayern Munich or probably play in another club. Although, many including me literally thought he was going to be signed out last summer transfer window, but he was still interested in playing for Munich. However, If his refuses to extend his contract and eventually choose to leave, I think Manchester City or PSG will suit him. Real Madrid focus are on Haaland and Mbappé.
Lewandowski is playing for Bayern Munich for almost 8 years now and there have been rumors around him wanting to leave the club after the season almost the entire time and i really think it was pretty close a couple of times already but back then Bayern always tried everything to make him stay at Munich and extend his contract which always worked out so far. Recently there have been strong rumors again that he wants to leave the club after this season again and that he already contacted his agent to make that happen.
This time could be different though, as Bayern Munich could be ok or even happy if he leaves this time. He still has 1 more year of contract which means they could get around 25 Million € of transfer fee for him and at the same time Haaland would be available for "only" aroun 75€ million € because of a clause in this contract, so the timing could be perfect for such an exchange of strikers after this season.
