Franck Ribery does not think Antoine Griezmann qualifies as world class just yet, but wants the Atleti man to impress at the highest level over a long period of time.
The France international has grown into a formidable striker since joining Atletico and could win the Ballon d’Or due to exploits for France at the Euro.
Nevertheless, Ribery feels his compatriot still has work to do before he can match the very best.
“Griezmann did a great job last season,” Ribery told Sport Bild.
“But you have to consistently show performances like that if you want to be world class. People are so quick to say someone is a fantastic player and deserves to win the Ballon d’Or after just one good year. I disagree with that.
“For me, you have to prove yourself over 10, 12 or 15 years if you want to be among the best. Do that and then I will congratulate you.
“I might have been out for nine months or so due to injury, but I have almost always been playing at the highest level over the past 10 years or so.”
