Barcelona's last Champions League match against Frankfurt (2-1) was not the best for the young winger Lamin Yamal, despite his active performance and continuous efforts throughout the game, he was unable to create any significant chances on his own.

However, the Spanish star managed to make his mark by providing a brilliant assist to Jules Koundé, who scored the winning goal, giving the team three valuable points that boost their hopes of making it into the top eight at this stage of the competition.

Despite his crucial contribution, Yamal left the field dissatisfied for two main reasons. The first was receiving his third yellow card at this stage, which means he will officially miss the upcoming match against Slavia Prague on January 21. This is a game in which Barcelona needs to win by a significant goal margin to prepare for any potential scenarios involving tied points.

The second reason for his anger was being substituted in the final minutes. The player appeared clearly upset both when leaving the field and on the bench, a scene that has repeated for the second time this season when he was substituted.

Coach Hans Flick commented on Jamal's reaction after being substituted: "He was a bit frustrated about being taken off, but he had already received a yellow card, and we needed fresh players. No problem with that. That's how things go. I understand him; everyone wants to play, and he believes he can play for 100 minutes. He's young. That's good sportsmanship. I don't see any issue with it. I was a player like him. I accept it."

Yamal continues to deliver outstanding performances this season, but his absence from the upcoming match represents a significant blow to Barcelona in one of their most important upcoming European games.
