Keane, a Sky Sports commentator, believes that Chelsea is rushing into a decision and should take a long-term approach rather than signing a high-profile goalkeeper due to fan pressure. He also warned that replacing Sánchez with Martínez could be a disaster and that the club might regret the decision.

The Premier League transfer window closes on September 1, and Chelsea will have to make a decision soon. Martínez has been linked with a move to Stamford Bridge after a string of errors from Sánchez, but Keane's comments suggest that the club should reconsider their approach.
