Saints rejected a deadline day bid from Swansea for Cork and he is happy he is staying at St Mary's.
"I think if you had asked me earlier in the season, I might have said something different," he said.
"Obviously Victor Wanyama came in and I wasn't playing as many games as I would like to have been playing at the start of the season.
"That changed in November, December time, playing a lot more games and I think it showed that I still had a part to play in the squad and in the team.
"Hopefully if I can keep the form going, I can still have a big part to play in the team. I will see what happens in the future and towards the end of the season."
