Coates has conceded his future could lie away from Liverpool.
He told El Observador: "I want to play, and most of all to be involved in the Uruguayan team like every other player.
"With that in mind I need to play, whether in Liverpool or somewhere else. I have a contract until 2016, but don't know what will happen in the future.
"I will wait until the end of the season and then speak to the club."
