Chelsea couldn't afford Capital One Cup shock, admits Jose Mourinho
Jose Mourinho admitted losing at Walsall was not an option after Chelsea's previous Cup shocks.
The Capital One Cup holders beat the Saddlers 4-1 to avoid an upset as their revival this season continued.
Ramires, Loic Remy, Kenedy and Pedro all scored to wrap up a comfortable third-round victory on Wednesday.
Chelsea were stunned 4-2 by Bradford in the FA Cup last season and, after taking just seven points from their first six games in the Premier League, boss Mourinho knew a win at the Bescott Stadium was vital.
"When you start the season with bad results like we did you cannot lose against a League One team," he said. "You can do that when the season is fantastic and you are top of the league, like happened last season.
"To lose a game against a League One team now would not be good for us. We don't need that bad feeling now, we need good feelings. The team was strong, played well and I'm happy with the result."
Mourinho was clearly unhappy at Diego Costa's suspension as he bit his lip to avoid a ban of his own.
Costa was hit with a three-game ban by the FA on Tuesday over an incident, not seen by referee Mike Dean, where he appeared to raise his hands to Arsenal defender Laurent Koscielny in Saturday's 2-0 win over the Gunners.
On the same day Arsenal defender Gabriel won an appeal against his red card for confronting Costa after the initial incident at Stamford Bridge.
Mourinho said: "It's easier to accept an injury but this kind of situation goes deeper in feelings and the team is hurt."
