The Blues entered the Champions League opener with one win from five matches.
"I forgot the feeling. For so long we don't win a game, so good, a good feeling," Mourinho said.
"I am a fantastic manager when I win matches and I am a fantastic manager when I lose matches."
Despite an early missed penalty by Eden Hazard, goals from Willian, Oscar, Diego Costa and Cesc Fabregas ensured Chelsea had no problems in seeing off their Israeli opponents.
"The penalty we missed was a big test for us," Mourinho added. "When you start a game you have to win and after five minutes you miss a penalty, it is an extra negative episode and our reaction was very good.
