The 33-year-old seems to have become more aggressive in recent weeks, having recently been shown the first red card of his Barcelona career, and also locking horns with his opponents on the weekend once more.

He score the winner in Barca's 2-1 win over Bilbao on Sunday, but also clashed with some of the opponents' substitutes.

It started with Messi himself being fouled, an incident that enraged the opposition bench, with some sarcastically shouting "you can't touch him" in direction of the match official.

According to AS, citing TV footage picked up by Jugones, the Argentine reacted by indicating his disagreement with the Athletic players, with some of the visiting substitutes shouting towards Messi: "shut your mouth, fool." 

Messi, though, was not prepared to back down either, yelling "Moron(s), what did you eat?", which could be interpreted as "what's making you behave so stupidly?", as explained by AS.

The Spanish publication also clarified that the Athletic bench's actual insult was "bobo", which is usually translated as fool, idiot, simpleton, etc., while Messi shouted "boludo", an insult common in Argentina, Uruguay and Paraguay, which is usually translated as idiot, moron, etc.

The Blaugrana captain, however, had the last laugh after Antoine Griezmann's second-half winner ensured that Barca secured all three points to move into second spot on the LaLiga log.
