Chelsea head coach Liam Rosenior took full responsibility for goalkeeper Robert Sánchez's costly mistakes in Wednesday's 3-2 Carabao Cup semifinal loss to Arsenal. Sánchez's errors directly led to two early goals for the Gunners at Stamford Bridge, leaving the Blues with a significant deficit to overcome in the second leg.

Rosenior defended his goalkeeper publicly, explaining he had asked Sánchez to play a new style of possession football that contributed to the blunders. The coach's stance aims to protect his player's confidence, a crucial factor for a goalkeeper under intense pressure in a high-stakes London derby.

Despite the defeat, Chelsea showed resilience by rallying late with two goals from Alejandro Garnacho to keep the tie alive. The team now faces an uphill battle at the Emirates Stadium next month, hoping for the return of key players like Cole Palmer to help overturn the first-leg deficit.
