There was drama outside Barcelona training ground as angry fans attacked Antoine Griezmann over statements his uncle made about star player Lionel Messi.

Emmanuel Lopez had commented that Messi is not working hard enough in training which is affecting other players.

“Griezmann was convinced that he wasn’t going to be successful within the first six months, but what I didn’t expect was that it would last an entire year. Besides, with Messi, I know what’s going on inside the club – it’s not easy.” Lopez said, according to reports from givemesport.com.

Some Barcelona fans were not happy with the statement and stormed the training ground to tell Griezmann to show some respect to Messi if he wanted to remain with the La Liga giants.

Antoine Griezmann joined Barcelona last season from Atletico Madrid but the World Cup winner has been inconsistent at the club, scoring 11 goals in 42 appearances.
