Suarez admits he's discussed things with both Kenny Dalglish and Brendan Rodgers.
He told the Mail on Sunday: "Yes, of course. I'm trying to change and to avoid doing it because I know that football is different here, and it's helping me at the same time. I've discussed it with both managers I've played under here, Kenny Dalglish and Brendan Rodgers.
"Kenny also used to tell me not to protest so much, that I should focus more on playing football, that I have a lot of qualities and so should forget about referees. And Brendan has also told me a few things to help me improve."
