Inter Milan striker Romelu Lukaku was involved in a heated exchange with his teammate Nicolo Barella.

The two were butting heads during Inter's 0-0 draw against Sampdoria on Monday.

Lukaku was gesturing to Barella to stop flapping his arms around constantly.

He is said to have shouted, per the Daily Mail: “Don't do that, enough with these arms! Do not do that! It's not good, it's insulting, now stop!"

Barella unleashed a response, which Lukaku did not appreciate, leading to him saying: “F*** you, son of a b***h" to Barella.

Post-game, coach Simeone Inzaghi stated: “These things happen on the pitch, they shouldn't happen and I don't like to see them."
