"His consistency this year has been phenomenal," said the Reds boss.
"He is a remarkable man. What I have admired from close hand is this is a guy who is trying to change.
"He has come in here and been labelled many things - sometimes maybe, for me, as because he is a foreign player he will get accused more.
"If a British player dives we'll laugh and find it funny but when it's Luis Suarez he is a diver.
"But this is a guy who is trying to turn around his life and adapt to the culture and you can clearly see that."
