Gustavo Abreu, an Argentine member of the Court of Arbitration for Sport (CAS), has urged the national country's talisman, ​Lionel Messi to apologize for his harsh comments on the recently concluded Copa America, in order to avoid a sanction from CONMEBOL.

The 32-year-old found himself a subject of controversy after he ​criticised the authorities following his red card dismissal during Argentina's 2-1 win over Chile in the third place playoff, with the superstar also taking a dig at the officiating during their loss to Brazil in the semi-finals, where he claimed that the tournament was fixed in favour of Brazil.

It later emerged that CONMEBOL were not too impressed by Messi's accusation and that they could penalise him for his comments, something which Abreu believes could be avoided by an apology.

"I'd advise Messi to apologize because they're going to shake him with a sanction. He should apologize so they don't hit him with everything," he said to Club Octubre radio, as quoted by ​Dailymail.

Abreu also suggested that the Argentine Football Association should contact Messi and ask him to apologise in a rant that we not usually associate with the five-time Ballon d'Or winner. The Barcelona star endured another frustrating campaign with his country, but did pick up an individual honour as he was awarded the ​Balon Educativo de Scholas, for his performances in the competition.
