"I can only repeat what I have already said before and that is that Messi is the best in the world at the moment. It pains me to admit it, but it's the simple truth," he said.
"I am not saying that Messi is on another level than Cristiano, though. But he's more decisive at certain moments when the team really needs him. He can salvage a game by himself.
"They are arguably the two best players in the world, but when it comes to my personal preference I must admit that I like Messi more."
