According to an interview with the Daily Record, Gunnarsson said: "I haven't heard anything more about Celtic other than the fact they are still watching me at Coventry.
"Celtic are a big team with a fantastic support and are regularly in the Champions League. That makes them an attractive proposition for any player. I'm young and have plenty of time to think about it.
I hope to play at Hampden and if I play well I don't think that would do my chances of moving to Celtic any harm."
