Benitez's hopes of winning his first Chelsea trophy were hanging by a very thin thread on Wednesday after the Blues put in a terrible performance to go down to a 2-0 home defeat in the first leg of their Capital One Cup semi-final.
Swansea had to work very little to achieve their victory. Two glaring errors from Branislav Ivanovic allowed Michu and Danny Graham to score, while the Chelsea team as a whole performed poorly.
Chelsea's fans made their disagreement with Benitez's decisions known throughout, booing the Spaniard and mocking his decision to leave Demba Ba and Frank Lampard on the bench.
But the Blues interim boss refused to single out any of his players for criticism after the match and insisted he was relatively happy with his team's performance.
Benitez said: "The team are doing well. You can lose a game and then analyse it, but if you play this game 10 times maybe you will win nine of them.
"I think the team were doing really well, had a lot of chances and could have scored two or three in the first half, but we made two mistakes and paid for them.
"I can see any player making mistakes and it's not an issue. It's about trying to do things afterwards, and Ivanovic tried to do his best. We carried on and tried to do the right things."
Chelsea's fans "You're not welcome" towards Benitez after Graham put Swansea's victory beyond doubt in the dying minutes and the Blues faithful again chanted the name of Spaniard's predecessor Roberto Di Matteo throughout.
They barracked Benitez for failing to introduce Ba earlier after Fernando Torres put in perhaps his worst performance of a woeful season.
The fans also hit out at Benitez for his failure to start the in-form Lampard, but Benitez refused to be drawn on the home crowd's criticism.
"You analyse all these things because we lost," Benitez responded when asked about the criticism from the stands.
"We have to concentrate on our jobs."
Benitez was unhappy that Ba had a goal ruled out in the final stages of the game for offside when he appeared level and also criticised referee Anthony Taylor for booking the Senegal striker for an apparent dive while going for a penalty.
"The goal was a goal, he was level," Benitez said.
"The penalty and yellow card, it wasn't a yellow card. The penalty depends on the decision of the referee."
