Pogba has had a difficult season under Jose Mourinho at Manchester United, and Leboeuf believes it could come to be similar with 'Les Bleus' under Didier Deschamps.
"He's under lots of pressure and he's been heavily criticised", Leboeuf told 'ESPN'.
"I don't think he's going to start against the United States on Saturday and I'm not sure he's going to start in the World Cup. [Corentin] Tolisso is above him on the left side. I think [Blaise] Matuidi is above him.
"I mean [he] has the talent, but we don't see it for the national team for the past two or three years.
"Pogba talks about winning the Ballon d'Or and put himself in the situation where right now he cannot [back up] what he says.
"I think he's a good guy and I think he has the talent, but he puts too much pressure on himself saying he wants to be the Ballon d'Or, that he was the key of the national team, that he wants to be the No. 1. Just don't say anything, just work hard."
