Former Inter Milan coach Frank de Boer has taken aim at Gabigol.

Gabriel Barbosa is now with Santos on-loan.

"Gabigol thought he was still in Brazil and would walk rather than run," De Boer told ESPN.

“He wanted to receive the ball without running into space, he didn't understand that he had to train hard. It's no coincidence that with me he practically never played for Inter.

“He has to look at himself in the mirror, prove every day that he can be the best or at the very least a good player, not thinking himself a superstar.

“After all, he only won the Olympics with Brazil and that's it… He has to prove to himself, his teammates and the Coach that he's a good player.

“The potential is there to be a fantastic player, as he has a great left foot, but European football is not the same as in Brazil. I hope he can learn that soon, otherwise it'll be a loss for Brazilian football too."
