I wonder if his salary was reduced, I think so. After all, his age is very serious. On the other hand, Barcelona has no choice because if Lewandowski leaves, Barcelona will only be able to sign a free agent (who will still have to pay a signing bonus) and there has long been a shortage of such among top strikers.
Lewandowski has good statistics, but last season he led the team in missed scoring chances, I don’t think there have been any radical changes this season.
An additional 1 season is considered appropriate because Barcelona also needs a new striker who is younger, more ambitious and sharp. Now they already have left and right wings, so the next transfer market will be the right time for Barcelona to find a replacement for Lewandowski. His age is getting older it will be risky if extended. I know he is temporarily the top scorer in La Liga, leaving 3 goals from Mbappe, it is possible that position can be taken by Mbappe at the end of the season.
Even though Lewa is older, he can easily play for another year in Barcelona. They are very good as a team and Lewa is still very effective. As far as I know, Barcelona has financial difficulties and cannot buy players with big budgets. It should be aimed at getting maximum benefit from what is available. He may even sell players next season. In this regard, teams such as Psg and City are always following the youth games in Barcelona.
In addition, Lewandowski, who is considered to be old, has 19 goals in the league. As long as he feels ready and good, he can play comfortably in Barcelona and La Liga. I think La Liga is not a league that requires high effort like the Premier League. Anyway, if he doesn't stay with Barça next year, his next stop will be either the Arabian league or the Turkish league. Most likely it will be Arabia.
