Chelsea interim manager Guus Hiddink says he is "happy" with the 2-0 win against Scunthorpe United in the FA Cup.
The Blues were far from their best but the Dutchman's men still manage to reach the fourth round of the competition.
"I was happy with the result," Hiddink is quoted as saying by the BBC.
"The Premier League is difficult to get the fourth place, but the other projects are the FA Cup and the Champions League.
"It is a decent result against a very strong opponent, especially in their set pieces. We started well, but we forgot to kill it off. It is good to be in the next round.
"We had high pressing, but we were a little bit arrogant in finishing off.
"The temptation [to make more changes to the starting line-up] was there, but the will was to not have the same experience as last year when they were kicked out in the early stages.
"[Diego Costa injury?] It's a contusion, we have to wait 24 hours to see how it settles down."
