Guus Hiddink has not had a problem with Didier Drogba's attitude since he became Chelsea's interim boss.
The Ivorian striker hit a late winner against Portsmouth to keep Chelsea's faint Barclays Premier League title hopes alive and earn Hiddink a fourth straight win.
Drogba ran to the bench to celebrate his goal and Hiddink added: "He is very happy with his goal. He knows he has not scored many goals this season. It gets rid of a bit of tension."
He added: "When a player is playing in that position and not scoring, then it comes to such an emotional explosion.
"If you are a striker you like to score. They live to score and to assist."
Hiddink believes the fighting spirit of the players is driving them on to try and catch leaders Manchester United.
Chelsea remain in second place, ahead of Liverpool on goal difference, but while they narrowed the gap to United to four points, Sir Alex Ferguson's side still have two games in hand.
"What is good in this team, is that they react when there are difficulties," said Hiddink. "Many players react in a way I normally don't like but this team is not happy when things are not going well and they make an extra effort to get their rewards.
"I notice there is a desire to have success and we have some key players who are demanding a lot from themselves and also from the other ones, which is key for big players with a big status.
"They challenge each other and it is very open. It shows the team is not fed up and has desire. It was very important to get three points because if we want to keep up the pressure, we have to win."
