Barcelona forward Neymar's feud with Granada's Ruben Vezo on Saturday spilled over into the tunnel and on Monday, a video emerged of the Brazil star pushing Vezo down a small flight of stairs.
As the two players were leaving the pitch following Barca's narrow 1-0 win against the last-placed side in La Liga, Neymar, who was walking alongside David Barral, pushed Vezo down the stairs.
Asked about the incident during Monday's news conference, Barcelona coach Luis Enrique would not be baited, only saying: "What a boring question. We're here to talk about tomorrow's game, I'm not interested."
Vezo, who is on a season-long loan at Granada from Valencia, had shared more than a few words with Barca's Brazilian star towards the end of the game.
The two players were both booked in the 87th minute after a Neymar challenge on one his teammate's did not sit well with Vezo.
Angered by what he'd seen, he squared up to Neymar, going head-to-head with the 24-year-old as they both exchanged insults.
The video has shown that Barca's No.11 was not prepared to leave what happened on the pitch, with the footage showing him pushing Vezo as he made his way back towards the visiting dressing room.
Neymar was the centre of the attention after last weekend's dramatic win over Valencia. It was his insults to the home team's supporters at Mestalla which Los Che have claimed led to the bottle being thrown at the celebrating Barca players.

An argument ensued throughout the last week, with both La Liga president Javier Tebas and the Spanish FA's [RFEF] competition committee suggesting, without naming, that Neymar was responsible of provocative behaviour.
Barca have since responded by complaining about the comments from both parties to the Administrative Court of Sport (TAS).
