Pep Guardiola has expressed his frustration regarding player injuries sustained during international friendlies, particularly highlighting the case of Manchester City's John Stones. The City manager revealed that he has "never been so angry" as when Stones was injured while representing England in a friendly match against Belgium earlier this year. Guardiola emphasized the need for players to prioritize their club commitments, stating, "If it's a friendly game, you cannot come back injured. I'm sorry. You are focused. In a friendly game, you cannot come back injured when you're playing in the quarter-finals of the Champions League." His comments reflect the high stakes and pressures faced by clubs during critical competitions, underscoring the importance of player health and availability.
