Another player making a return is Raphinha, who has been out since September with a hamstring injury. Flick expects Raphinha to be back in action for the match against Athletic Club.

However, forward Marcus Rashford is a doubt for the match due to a fever. Flick is keeping a close eye on Rashford's condition and will make a decision about his availability closer to the match.

The team's return to the Camp Nou is also a welcome development for Flick. The team played their home matches at the Olympic Stadium for the past two seasons, but they have now returned to their home stadium. Flick believes that playing at the Camp Nou can give the team a big push in the match, as the fans are very supportive and know exactly when the team needs a boost.

Flick is looking forward to the match against Athletic Club and is confident that the team will give it their all. The match is set to be an exciting one, and Flick is optimistic about the team's chances.
