Torres netted his first double for the Blues since his record-breaking January move from Liverpool in Wednesday night's Champions League thrashing of Genk, taking his tally to four goals from his last four games.
His previous two strikes this season against Manchester United and Swansea had been marred, respectively, by one of the worst misses in Barclays Premier League history and the Spaniard's first red card in English football.
At the double: Fernando Torres netted twice in Chelsea's 5-0 win against Genk
And although he might easily have had a hat-trick against an injury-ravaged opposition, the 5-0 win over Genk was easily Torres' most trouble-free outing in a Chelsea jersey.
Defender Ivanovic, who joined his fellow 27-year-old on the scoresheet with his first goal of the season, said: 'I always said there is no question about Fernando Torres because he is really great.
'He showed every day his professionalism on the training ground, how he is working hard for the team and everyone is really happy when the ball comes to him.
'As a team, we expect more goals from him this season. It is important to have the big squad and the big players who can decide games. Fernando showed his quality in his play and how he will fight for the team. We are happy with that.
'We have great options up front and it is important for all of the guys to be ready for the competitions and always show their best on the pitch to get the best results for the club.
Off the mark: Defender Branislav Ivanovic also scored his first goal of the season
'We started the season with everyone fresh and motivated. This is going to be the key for this season. The motivation is most important.'
Ivanovic refused to get carried away with Chelsea's start to the season, which has seen them pick up the same number of Premier League points as the same stage last term - a campaign that famously saw them fall away. 'We have the confidence. We are growing up as a team every game,' he said.
'But this season is long and you have to be ready and play like this performance every game, which is very hard. We will try to do this all season.We have a very big London derby game and, after that, we go game by game.
'The games against Arsenal and Liverpool will show how good we are as a team for this season. I think we have grown up as a team every game, but this is the biggest test.'
