The 42-year-old is at the top of the Barclays Premier League sideâ€™s recruitment list after chief executive David McNally took the unusual step of admitting he is already sizing up possible replacements for under-pressure manager Chris Hughton.
"I canâ€™t do anything about speculation. It is always flattering but it would be wrong of me to make any sort of comment on it at all at the minute.
"Iâ€™m very lucky to be the manager of Celtic. Itâ€™s a privilege; Iâ€™ve done it for almost four years now so Iâ€™m just getting my teeth into it.
"Iâ€™ve got a lot of challenges that lie ahead for me in the occupation that Iâ€™m in.
"Iâ€™ve got a big job on my hands, a rebuilding job to do and weâ€™re not far away from winning another title and thatâ€™s always very important."
