Lionel Messi Hits Back At Antoine Griezmann's Uncle's Barcelona Training Claim

And he was asked about comments made by Griezmann's uncle who said training sessions at Barcelona are designed to make the 33-year-old look good.

He said: "The truth is that I'm tired of always being the problem of everything at the club."

Griezmann has failed to settle at the Camp Nou since his £108 million transfer.

The player's uncle stoked the rumour by hitting out at Messi.

"Griezmann was convinced that he wasn't going to be successful within the first six months, but what I didn't expect was that [his struggles] would last an entire year," he said.

"Besides, with Messi, I know what's going on inside - it's not easy.

"Basically, [Messi] doesn't work hard enough at Barca and the training sessions are structured in order to please certain people, which is fine if you don't want to work.

"Antoine needs to work, even though others don't need as much effort to play well.

"He's the other way around - he needs to put in a lot of effort for himself."

Barcelona, who occupy eighth place in La Liga, resume their faltering league campaign away at Griezmann''s former club Atletico Madrid on Saturday.
