Juventus coach Massimiliano Allegri has publicly criticised Alvaro Morata after their friendly win over Lechia Gdansk.
Morata was hooked at halftime of the 2-1 victory.
"It wasn't Morata's day and I didn't like his attitude," said Allegri.
“Regardless of technical errors, what really did not go well today was his attitude. When something didn't work for him, he just stopped.
“That is why I asked him to get off the pitch. He made me angry on the pitch, but then he was good as he went off to train by himself.
“There's a bad atmosphere at Juve, as everyone says we are the favourites, but that is not the case. This year will be even more difficult.
“Before this atmosphere contaminates us, we have to stop it right from now."
