FC Barcelona head coach Hansi Flick has expressed regret over midfielder Fermin Lopez's recent thigh injury, which he believes could have been avoided with better communication regarding player workload during international duties. Lopez's injury, sustained while representing Spain's U21 team, will sideline him for three to four weeks, adding to Barcelona's injury woes which also include key players like Dani Olmo, Ronald Araujo, and Frenkie de Jong. Flick acknowledged his responsibility in not consulting with the U21 coach, stating, 'I feel a bit guilty because we could have spoken with the U-21 coach.' Despite these setbacks, Barcelona has started the season strongly, currently leading La Liga with a perfect record. The team now faces a challenging UEFA Champions League opener against AS Monaco without several key players. Flick emphasized the importance of careful management and rotation of players to navigate the ongoing injury crisis.
