Celtic midfielder Nir Bitton is ignoring rumours linking him with Sunderland.

The former Ashdod star is being tracked by Sunderland, but insists he's happy where he is.

"I don't know anything about Sunderland," said Bitton. "That's not my job - my job is to help Celtic win trophies.

"I'm really happy here. I have been here two seasons. My wife is happy and we just need to do something with the weather!"
