An uncle of Barcelona striker Antoine Griezmann says his nephew doesn't get along with Lionel Messi.

The comments made on El Chiringuito arrive just days after long time adviser Eric Olhats also blasted Messi for making Griezmann's time with Barca difficult.

His uncle said, "He was convinced that he was not I was going to be successful in the first six months, but what I didn't expect was that it would last a year. Besides, with Messi I know what's going on inside. It's not easy.

"So what's going on inside? There are things that you can't always say. Basically, at Barça, you don't work hard enough and basically the training sessions are made to please certain people.

"Antoine needs to work even though some people don't need a lot of effort to be well. Griezmann is the other way around, he needs a lot of effort to be well."
