West Ham United coach Kevin Nolan had to be held back from Brentford star Neal Maupay.
The two teams went head to head in the Premier League on Monday night, with the Hammers winning 4-2.
Maupay, who did score in the game for his side, was winding up Nolan on the sidelines late in the game.
Footage showed the two arguing and coming close to a physical altercation, before others got in the way.
While commentating, Manchester United legend Gary Neville had a say on the matter.
He said: "The Brentford striker, apparently, we believe was outside the referees room [at half-time] and Nolan has taken offense to it."
