Sergio Aguero comes to the defence of best friend Lionel Messi after he was threatened by Canelo Alvarez

Sergio Aguero has jumped to the defence of Lionel Messi after Canelo Alvarez shockingly accused him of disrespecting the Mexico shirt and flag.

Argentina needed to bounce back after their shock defeat to a Saudi Arabia side ranked 51st in the world in their opening game.

They did just that and there were wild scenes in the dressing room afterwards, with chants and dancing.

In the celebrations, Messi appeared to accidentally kick a Mexico shirt across the floor while taking off his boots.

He had swapped shirts with a Mexico player and so had the green jersey with him.

“Did you guys see Messi cleaning the floor with our jersey and flag,” he tweeted.

“He better pray to God that I don’t find him. Just like I respect Argentina, he has to respect Mexico!

“I’m not talking about the country as a whole, just about the bulls**t that Messi did.”

Fans hit back at Canelo's comments and told the 32-year-old he was seeing things.

But former Argentina and Manchester City striker Sergio Aguero, Messi's best friend and long-time roommate, felt the need to reply.

"Mr. Canelo, don't look for excuses or problems, surely you don't know about soccer and what happens in a locker room," Aguero wrote on Twitter.

"The shirts are always on the floor after the games are over due to sweat and then if you see well, he makes the movement to remove the boot and accidentally hits it."

Argentina are second in Group C, one point behind next opponents Poland, who they face on Wednesday at Stadium 974.
