Liverpool Football Club player Suso has been fined £10,000 ($16,220, €12,300) for using the word 'gay' to insult team mate Jose Enrique on Twitter.
The Spanish midfielder, real name Jesús Joaquín Fernández Sáez de la Torre, posted a picture of Enrique getting his teeth whitened, with the comment: ‘What fuck is he doing?... This guy is gay. He has some mental problems. He does everything except play football.’
Despite quickly deleting the offensive comments, the 19-year-old's tweet has landed himself in trouble with the UK's Football Association.
The FA said in a statement: 'Following an independent regulatory commission hearing yesterday (17 December), Liverpool's Jesus Fernandez Saez (Suso) has been fined £10,000 and warned as to his future conduct for a comment posted on Twitter.
'The charge, which the player admitted and requested a paper hearing, was that he acted in a way which was improper and/or brought the game into disrepute in that the comment was posted on his Twitter account and included a reference to a person/s sexual orientation and/or disability.'
The Gay Football Supporters Network welcomed the FA's decision.
In a statement, GFSN Chair Chris Basiurski said: 'We hope that it will continue to be a warning to people in the game that homophobic comments are not an acceptable form of banter and that people should take greater care when using social media.
'However, in a time where resources to fight discrimination in football are limited, we would like to see the monies received by the FA in fines reinvested in the fight against homophobia.
'Not only would it serve as an appropriate punishment for offences, but also provide a positive outcome, with the fines used to fund some of the important initiatives needed in the game to spread the inclusive message.'
Earlier this year, the FA said to all players that comments on Twitter or other social networking sites which make 'reference to a person’s ethnic origin, colour, race, nationality, faith, gender, sexual orientation or disability may be considered aggravated and attract a higher disciplinary sanction.'
Suso’s comment also comes as former England player Gareth Southgate claimed that players would accept gay team mates in the changing room.
He said: ‘I’m sure there might be some reaction from crowds, but within dressing rooms I think it would be accepted.’
