Suarez is a contender for this season's Player of the Year.
Comolli told the Daily Express: "Luis has been incredible. Everyone knows about his skills, but look at his work-rate.
“There are no bad balls when Luis plays because even if a pass is 10 yards astray, he fights and makes it his. He says to defenders, ‘You are not going to bully me, I’m going to be on your back all day long and I will chase every ball’."
