The relationship between Neymar and Barcelona coach Luis Enrique is being questioned.
Neymar blew up last month over his substitution against Sevilla, with his histrionics upsetting senior Barca teammates.
Sport says the following day, which was a scheduled day off, Neymar was called in front of the Barca leadership group and told in no uncertain terms that he'd been out of order - not the least that the player who was replacing him was Xavi.
Two requests were made to the Brazilian - apologise to the squad as a group and also apologise to Enrique.
Neymar accepted the advice of the squad's leaders and waited for everyone to be together inside the locker room before the doors were locked. The Brazilian apologised, accepting he had not been respectful towards senior teammates and had shown the wrong attitude.
His apology convinced the squad, who all appreciated his show of humility.
However, the second request made to Neymar has been ignored. The attacker refused to apologise to the coach, insisting he had "nothing to tell" Enrique and has left the situation to smolder.
