Barcelona coach Hansi Flick has expressed his frustration about playing against Osasuna on Thursday right after the international break. However, he chose not to dwell too much on the issue.

The match was originally scheduled for earlier in March but was postponed following the passing of Barça's first-team doctor, Carles Miñarro, just hours before kickoff.

Now, Barcelona faces a tough stretch of seven matches in just 20 days. To make matters worse, they will be without Raphinha and Ronald Araújo, who are unavailable due to their participation in World Cup qualifiers in South America.

"I don't want to speak about my reaction, I think it's not good," Flick said in a news conference when asked for his thoughts on the match being rearranged for this week.

"Players have played for their national teams, but we have to play this match. We can speak about if it's the right time to play this tomorrow …

"We can also speak about playing Leganés away at 9 p.m. [on April 12 before the second leg of the Champions League quarterfinal against Borussia Dortmund]. When we play away, it's always at 9 p.m., so we arrive back late in the night.

"It's to do with recovery for the players. I am not happy with this. When you see other leagues with Champions League teams, it's different to here.

"When you play Champions League, it's not about Real Madrid against Barça, it's about protecting your Spanish teams. But we play, no excuses

"We accept this. It's a task for UEFA, for FIFA that they say after international breaks it's necessary that players have three days rest. LaLiga say we have to play and we say 'Yes, we do it.'"

Flick explained that he canceled two rest days for players who represented Spain, the Netherlands, France, and Poland during the international break to ensure proper preparation for the Osasuna match.

However, the game comes too soon for Raphinha and Araújo, as they are only returning to Europe on Wednesday. Additionally, Pau Cubarsí will not be fit to start after injuring his ankle while playing for Spain.

"Rapha and Ronald will not play," Flick confirmed. "They are out. They have a long flight. It's not the best way. They have to recover, train.

"And at centre-back, Eric [García] and Iñigo [Martínez] will start for us. Pau will be on the bench. I hope we won't need him because also it's better he has two or three days more. He needs it."
