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.
