Ajax coach Frank de Boer feels they meet Champions League opponents Barcelona with Lionel Messi in prime form.
De Boer is a former Barca player and is a big fan of Messi.
"He's broken so many records. It's incredible because he's still so young," he said.
"For me, he's the best player in the world, not just because of the goals he scores but also because he gives assists. He's very complete."
On former Ajax striker Luis Suárez, he said: "I like that fact that he's at Barcelona, because he's fought hard and ever since he was at Groningen he has tried to get better every year."
