The Guardian says Campbell continues to mull over manager Arsene Wenger's offer of a one-year contract to stay at the club.
Campbell would be happy enough to be a back-up next season but he must consider where he would rank in the central-defensive pecking order. Wenger will have Johan Djourou available again after injury and he is certain to add fresh blood in the position, in which he already has Thomas Vermaelen.
But Campbell needs to know whether Wenger will sign two new centre-halves and how that would affect him in what could be his last season as a professional. The 35-year-old has lucrative offers from elsewhere in the Premier League but he is happy at Arsenal.
