The veteran coach is not amused with the way the Catalans have managed the former Santos star since his arrival at the club
The 21-year-old was diagnosed with anaemia earlier this month after undergoing surgery to have his tonsils removed back in July and Scolari has slammed the Blaugrana for advising the forward to go under the knife and for the way they have managed Neymar since his arrival from Santos.
"It’s unacceptable that Neymar now has anaemia," Scolari said at a press conference.
"He was with Barcelona before the Confederations Cup and he was perfectly fine. At the moment it’s clear he’s not the same, though, because he underwent surgery.
"It seems it was that lot [Barcelona], who know everything, who think they are always right.
"It was always obvious Neymar was going to lose weight after the surgery."
Neymar joined Barca in a €57 million deal from Santos earlier this summer and has reportedly lost up to seven kilograms since his operation.
