Gary Cahill claims he is yet to reach his peak, and is hoping to fulfil his potential at Chelsea.
The England defender completed a £7million transfer to Stamford Bridge on Monday and is expected to make his debut against Norwich on Saturday.
The 26-year-old admits he has struggled to find form this season in a Bolton team fighting relegation, but has taken heart from his international performances.
Cahill said: "My form this season has been bit of a rollercoaster, but overall I've been pleased with the way I've been playing.
"For England I've been really pleased, whereas for Bolton it started dodgily before coming into my own over the last couple of months.
"By joining Chelsea from Bolton I'm jumping from one scale to another scale and hopefully having fantastic players around me will make my job easier.
"I've come from a team that is under a lot of pressure and doesn't have too much of the ball, and I'm not being disrespectful.
"With Chelsea you're in possession and on the front foot all the time. That will help me and you've seen that from me with England.
"It's great to be able to get on the ball and express yourself, whereas sometimes at Bolton we played a little bit more direct."
