There has been speculation that the 26-year old Wales international could head back to Cardiff if the Bluebirds gain promotion to the Premier League but he has made it clear that he is settled with the Glasgow giants.
"They are certainly looking good for promotion. They are top clear at the top and have an excellent squad. Malky Mackay has done a fantastic job.
"I haven't heard anything about a move at the moment so I can only assume it's just paper talk.
"I still have another year with Celtic and I'm happy with the way things have gone as it has been a brilliant season.
"You never know in football, anything can happen, but I'm happy here and am looking forward to next season.
"Everyone knows it's been a good season for Celtic and hopefully I'll be there next season. There is nothing new in terms of talking about a new deal.
"I've still got another year left so there's plenty of time.
"I think we'll wait until the end of the season. Hopefully I can continue at Celtic as it's a fantastic club and I really enjoy it and they've been brilliant with me."
