The Uruguay international was named Barclays player of the month after setting a new record with 10 goals in December, the first player to reach double figures in a calendar month.
Suarez has played only 15 league matches as he had to serve the remaining half of a 10-match ban for biting Chelsea's Branislav Ivanovic in April.
The season before that the 26-year-old was banned for eight matches after being found guilty of racially abusing Manchester United's Patrice Evra while he has also been accused of diving and has had his fair share of gaining advantage via handball incidents.
But having angled for a move away from Anfield in the summer Suarez has returned a more mature player according to his manager Brendan Rodgers.
"My temperament, attitude, desire and hunger when I am on the pitch has always been like this and will continue to be this way, I now know I have to control it more," Suarez told ESPN.
"An example of this was about two weeks ago when I had an open shot at goal and hit the post and it rebounded close to my hand and I was about to go for it and then I stopped.
"If the same thing had happened two months ago I would have gone for it. These things stay with me but I tell you I am changing.
"I am improving my attitude on the pitch because I know I was wrong in the past and I was creating an image of myself I know wasn't me."
