The Blues have been bolstered by the additions of talented midfielders such as Oscar, Marko Marin and Eden Hazard over the summer. Manager Roberto di Matteo has, however, seen the likes of Didier Drogba, Jose Bosingwa and Salomon Kalou depart the club and it's uncertain if the new-look Chelsea side will be able to integrate well enough for the new season.
Nevertheless, Cahill pointed towards the end of last season when the Blues registered a series of victories and won both the FA Cup and the Champions League as evidence that they have what it takes to be a dominating force in the Premier League.
And he brushed off concerns that Manchester United's acquisition of Robin van Persie would make the Red Devils too strong for the rest of the league. Many observers are tipping the Manchester duo of United and Manchester City as the favourites to win the title in the coming season.
"We are definitely title contenders with the squad we have got and the confidence we have because of what we did at the back end of last season. It will stand us in good stead going into this year," he was quoted as saying by the Sun.
"It is fresh at Chelsea. There are new signings and it will be exciting, especially if we can produce the form we did in the last two months of last season.
"Van Persie would have an impact on any team he plays for. You see his work and what he can do, last year especially. He would be a fantastic signing for anyone.
"Teams are getting so strong but we have added to our squad so hopefully we will keep up with that and we are looking to go about our business.
"Last year the league form was not what we wanted so it's important we address that this season and I'm sure we will."
Chelsea play Wigan on Sunday at the DW Stadium with the corresponding fixture ending in a 1-1 draw back in December 2011.
