Photos were published of a toilet cubicle covered in fake blood, with the accompanying reports accusing the Brazilian and his team-mates of behaving in a disrespectful manner at the Coliseum Alfonso Perez.

The images emerged after the Barca players had been heavily criticised for interrupting Victor Rodriguez’s post-match press conference dressed in Halloween costumes.
However, while the club released a statement apologising for that prank going wrong, Alves responded angrily to the reports the changing room was trashed.
“We didn’t dirty the locker rooms like that — someone has messed it up and said it was us,” the Brazilian said after Wednesday’s 3-0 win over BATE Borisov in the Champions League.
Alves then hit out at the fall-out which has followed the players’ decision to dress up after the victory against Getafe.
“There are more important things [than the ensuing criticism]," the 32-year-old added.
"Children are starving. You have to enjoy life.”
Barca’s win over BATE puts them within a point of the next round of the last 16 in Europe, but it came at a cost with Ivan Rakitic taken off with a calf problem in the first half.
The Croatian joins Lionel Messi, Rafinha and Douglas on the sidelines, while Thomas Vermaelen, Andres Iniesta and Sergi Roberto have only just returned to action.
“It’s wear and tear after a long time competing at a high level,” Alves said about the Catalan club’s injury problems.
“It’s happening in football, not only at Barca or Real Madrid. It’s an example that we are human, not machines. So many years competing takes its toll.”
