Eight members of Mexico'sCopa America squad were suspended last week for violating team discipline.

The players - Dos Santos, Nestor Vidrio, Israel Jimenez, Jorge Hernandez, David Cabrera, Marco Fabian, Javier Cortes and Nestor Calderon - were also fined 50,000 Mexican pesos (around £2,640) each.

Barcelona B midfielder Dos Santos, 21, told www.fcbarcelona.cat: "I'm here to face the music. I have committed misconduct.

"I am very sorry for what I did and I apologise to the team, my team-mates, the entire coaching staff and people of Mexico. I'm here and I assume responsibility."

He added: "I have to apologise to my club, and to my family.

"I have a very clean record - nine years at the club and there has never been any problem with me.

"I have always been disciplined but we are all human beings - we've all made mistakes.

"I've decided to participate with the Barcelona foundation and also do something in Mexico to offset the damage."

The Mexican federation did not disclose details of the incident, which reportedly took place after a 1-0 Copa America warm-up win over Ecuador, but said the players were sorry for their actions.
