Barcelona head coach Hansi Flick issued a stark warning to Europe after his side convincingly defeated Borussia Dortmund 4-0 in their Champions League quarter-final first leg

Barcelona head coach Hansi Flick has sent a clear message to the rest of Europe’s top clubs after his team delivered a commanding 4-0 victory over Borussia Dortmund in the first leg of their Champions League quarter-final clash.

The emphatic win at the Olympic Stadium on Wednesday night puts the Catalan giants in a formidable position heading into the return fixture.

Despite the convincing scoreline, which firmly places Barcelona in the driving seat to progress to the semi-finals, Flick maintained that his squad is not resting on its laurels and believes there is still scope for further improvement within the team.

“I want to keep improving. Today we saw some areas we can do better,” Flick told reporters during the post-match press conference.

“We will analyse this match thoroughly, and I will certainly commend the players for their excellent performance.

However, it’s crucial to recognise that there are still aspects of our game that we need to work on. I am very happy with the result this evening, but we must remember that this is just the first step in the tie.”

Flick’s comments suggest a relentless pursuit of perfection within the Barcelona camp, signalling a potentially ominous sign for their Champions League rivals as the competition progresses.
