The fullback said: "The manager (Luiz Felip Scolari) changed the way we play, he wants the fullbacks to attack. People used to say that was my game and I'm really enjoying attacking again.
"This is the best I have played since I came to Chelsea. He has given me a lot more opportunity to get forward. We have shown that the more me and [Jose] Bosingwa get forward, it is hard for the opposition to mark us."
The departure of left-back rival Wayne Bridge to Manchester City this month has put even more onus on Cole to play every match until the end of the season.
Bridge's role at Stamford Bridge after Cole's arrival was to act mostly as cover and to provide the opportunity for his team-mate to get a rest on occasion.
But Cole prefers to play every week, adding: "I'd rather play every game, it's better for the brain and keeps me fit."
