Arsenal defender Campbell flattered by Celtic interest
A switch to Parkhead would appeal should things not work out with the Gunners.
"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," Campbell told ESPN Soccernet.
"Although a one-year contract has been offered, these things take some time to thrash out - and I imagine Arsene has quite a lot to deal with at the moment, particularly with Fabregas."
Campbell added: "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."
