Barcelona continued their impressive run of form by beating Galatasaray 4-1 in Istanbul , securing their 10th consecutive victory of the season.

However, Hansi Flick’s side has another European concern to address after conceding yet again in the Champions League.

As such, the Catalans have now gone 17 consecutive matches in the competition without keeping a clean sheet, a streak that stretches back to April 2025.

While their attacking output has helped them maintain their winning momentum and has eased pressure on defenders, the repeated defensive lapses could become costly against stronger opposition.

Notably, Barcelona recovered emphatically after falling behind against Galatasaray, but the goal they conceded offered another reminder that their work without possession remains unfinished.
