Interim manager Rafa Benitez feels Chelsea have improved since his arrival at Stamford Bridge.
The former Liverpool boss was feeling the pressure after his side recently suffered back-to-back home defeats in the Premier League and the Capital One Cup to bottom-placed QPR and Swansea respectively.
However, the Blues responded with a 4-0 drubbing of Stoke at the Brittania Stadium on Saturday.
And Benitez, who replaced sacked fan-favourite Roberto Di Matteo in November, was naturally pleased with the result, which lifted his charges to third place in the standings.
"The team is doing well, the players are happy," said Benitez.
"The players are training really well and you can see that they're trying to perform. All the staff are doing a great job so the atmosphere in the side is really good.
"When we play the games we cannot control what's going on outside the pitch but we'll try to do our best on the pitch and hopefully it will be easier.
"We cannot every week be thinking crisis, not crisis. We're scoring more goals than in the past, we're conceding half of the goals that the team has conceded in the past.
"That means we have more balance and that is the way to sustain the performance of the team at this level."
