Sol Campbell has refused to rule out a move to Celtic, while Hull have paved the way for Jimmy Bullard to join the Hoops on loan next season.
Campbell, 35, is keen to remain at Arsenal and has impressed after his return to his old club on a short-term deal during January. A new contract is on offer for the veteran, but has not yet been formally agreed and reports on Wednesday claimed Celtic are set to make a surprise summer swoop.
Campbell said on www.espnsoccernet.com: "I am in no rush, I would like to stay with Arsenal if I could. However, Celtic are a massive club, a great club, with massive support."
He added: "I worked very hard to get back to my best and to play in the Champions League again, and I would love the opportunity to continue at Arsenal.
"Although a one-year contract has been offered, these things take some time to thrash out."
Meanwhile, Hull would consider letting record signing Bullard join Celtic on loan if the Clydesdale Bank Premier League side made an approach.
Bullard is thought to be one of a number of high-earning players the Tigers are keen to offload following their relegation from the Barclays Premier League.
Hull claim Celtic are interested in the former Fulham and Wigan midfielder but the 31-year-old's injury record may deter clubs from seeking a permanent move.
Head of football operations Adam Pearson told the Daily Express: "We are aware that Celtic have an interest in Jimmy Bullard. They haven't made a direct approach to me but I know officials from Celtic have spoken to a number of people on our coaching staff about Jimmy Bullard.
"Everyone is aware of our financial predicament and we would have to consider all offers. If Celtic were to make an offer for Jimmy Bullard, whether it be a permanent transfer or a loan deal, then it is something we have to give serious consideration to."
