Liverpool travel to Old Trafford this afternoon looking to close the gap on leaders Chelsea after they slipped up at Aston Villa yesterday.
Suarez has been a major cog in the Reds side again this season, with his partnership alongside Daniel Sturridge being one of the main reasons for their fine form.
Rooney has admitted that he has compared himself to the Uruguayan striker at times but believes Suarez is up there with the best in the world at present.
“Luis Suarez is an incredible player. He’s unique in the way he plays and, on current form, he’s up there with Ronaldo and Messi,” Rooney said.
“People say Suarez is a street footballer like me, but I’d bet where he grew up in Uruguay was a lot tougher than where I grew up in Liverpool.
“Anyone who knows football can see he’s got that fight and desire in him. He’ll do anything to be successful.
“Now and then it all goes wrong for him, but as a footballer, I can’t help but admire him.”
