Hansi Flick sounds the alarm as Barcelona face red-hot Celta de Vigo before international break

FC Barcelona enter Sunday's LaLiga clash against Celta de Vigo with a warning from their own manager.

Head coach Hansi Flick did not mince words when previewing the trip to Vigo - a notoriously tough venue and home to one of Spain's most in-form clubs.

" Celta is in a good moment of form, perhaps in a better situation than us," Flick admitted. "Everything will depend on our attitude. We want to win and go into the break with three points." Those comments mark a concerning tone for a Barça team struggling to maintain momentum and consistency, especially compared to a surging Celta de Vigo side.

Celta is rolling and Barça is searching

Barcelona 's opponent on Sunday has won five straight matches across LaLiga , the Copa del Rey, and the Europa League . Under young coach Claudio Giráldez, Celta have become unpredictable - a team that rotates lineups fluidly and plays without fear.

Meanwhile, Barça is still trying to find defensive structure and rhythm under Flick . The German coach pointed to recent issues that have allowed opponents too much space: "In Bruges we saw that our defensive line sometimes drops too deep. The forwards are further away than they should be. We need to be more connected - with and without the ball."

This matchup comes right before a crucial international break - the last one until March - making the stakes even higher for Barcelona to repair confidence and collect points.

Injuries add to Flick's concerns

The squad remains thin in key spots:defender Jules Koundé is a major doubt, having failed to finish the team's final training session. Missing him would put even more pressure on a Barcelona back line already under scrutiny.

Friday brought a fleeting emotional lift: more than 21,000 fans attended an open training session at the renovated Spotify Camp Nou . Flick was struck by the atmosphere: "The first impression was fantastic. You could feel the history of the stadium. Once we're able to play there, it will definitely help us."

But the reality remains: Barcelona must prove that feeling can translate into results - starting immediately. Barça need confidence heading into the break, while Celta are pushing into European contention. The title race could tighten fast if Barcelona stumble
