Barcelona hero Rivaldo has warned Atletico Madrid attacker Antoine Griezmann over a move to the Nou Camp.

The Brazilian acknowledged that playing next to a superstar such as Lionel Messi would not be ideal for any top-level player.

"I am not disappointed that Griezmann did not sign for Barcelona as every player has his own way of seeing things," he said.

"There are many great players at Barcelona and it's hard being in Messi's shadow.

"[Griezmann is] a world champion that I like very much as a player."
