Gutierrez knows the £23million former Ajax star will always have his detractors, but he isn't among them.
He said: "He's someone I know, and I realise Suarez upsets some people - he's done a few things that players and others don't like too much.
"He does a lot of things that make people talk about him and not about his football, but I'd rather talk about what kind of player he is.
"He's so excitable, I don't know whether that's a particularly South American trait, but when you see a referee make a decision against him, he's always upset.
"We know that he's a really difficult striker to handle, and his work-rate is up there with the best, so we know we'll have a tough time keeping an eye on him."
