Cork has just three starts this season in an impressive Southampton side and he said that the next couple of weeks could decide whether he opts to fight for his place or move on.
"Obviously, I've been thinking about what part I'm going to play in this squad," he is quoted by Sky Sports News as saying. "I haven't played that much, so it's going to cross anyone's head to think 'what use am I going to be in the squad?'
"I'll see what happens in the next couple of weeks and see if [the manager] uses me. I'm always happy to be part of the squad and play whenever I'm trusted."
Cork moved to Southampton in 2011 from Chelsea.
