NEYMAR and Barcelona assistant Juan Carlos Unzue were involved in a heated training ground bust-up after being told he would end up like party-loving Ronaldinho.
The 25-year-old scored in their 4-1 win over Villarreal over the weekend - but it has emerged he had a row with Luis Enrique's No2 before the victory.
Neymar took a trip to London last week with his sister Rafaella and has also been suspended in recent months, including for Barca's breathless 3-2 Clasico win over Real Madrid.
According to Mundo Deportivo, the Nou Camp superstar had a falling-out with Unzue over Neymar not applying his tactical ideas in training.
But it has later emerged it he was told: "If you continue this way, you'll end up just like Ronaldinho."
A spat soon became more and more heated and Unzue, 50, allegedly gave the forward a sharp dose of reality.
Staff were forced to intervene in the row and Neymar left the training ground in a foul mood.
The Catalan publication also note how he is happy to tell the players exactly what is on his mind, a skill that could stand him in good stead if he is hired as Barcelona's new manager over the summer.
Marc-Andre ter Stegen, Ivan Rakitic and Samuel Umtiti have all been on the end of a tongue-lashing this season by the disciplinarian this season.
Previous reports have suggested Neymar favours Unzue to take over from Enrique, with players and staff applauding his methods.
Yesterday, rumours emerged that former Barca boss Pep Guardiola is interested in bringing Jordi Alba to Manchester City in the summer.
Alba reportedly does not fancy working under Unzue and after five years at the Nou Camp could push for a change.
