Barcelona‘s new-signing Junior Firpo has had a lot of explaining to do regarding some of his old tweets against Argentine forward Lionel Messi.

The Real Betis academy graduate admitted to saying offensive things about Messi when he was 15 years old but believes that it is now in the past.

Firpo then claimed that he could “probably break both of Lionel Messi’s legs” with “one kick” and called the Argentine a “son of a bi**h” among other things.

“I see him every day in the changing room,” Firpo told SPORT .

“I know you’re asking this because of the old tweets I made but that’s in the past and we’ve squashed that. It isn’t something I want to make a bigger deal out of.

“I don’t think he even knew. I was a kid who came through the academy at Betis and I don’t think Messi is going to care about that.”

The left-back is confident that the past doesn’t matter now and he will be apologising to the Barcelona star.

“It’s something that doesn’t matter and that I can explain without problem,” Firpo told  Mundo Deportivo .

“They are things that are done at 15 when nobody knows you and when you cannot think that this will have an impact years later.

“I have to apologise and I do it humbly and without problems.”
