Tru but unfortunately:
If he does not reach a certain percentage of matches between now and the end of the season, it will be Barça who can unilaterally terminate his contract.
"The two parties agree that, in the event that the participation ("matches played") of the PLAYER during the third season (2024/25) is less than 55% of official matches, FC BARCELONA will have the right to terminate this employment contract early."
The text also specifies that a "match played" will be any match in which he is a starter or in which, without being a starter, he reaches 45 minutes.
The Polish striker has already played 31 of the 34 games played by the team this season, but Barça could end up playing a total of 51, which means that, for the moment, he has 50.8% of official matches, the only ones that are counted.
To exceed 55% and leave the club without any option of terminating his contract, he would have to play three more games. So things stand, Lewandowski can be much more relaxed than he was already because the striker is a regular for Flick and, in that sense, he had more than signed the fourth year of his contract.
