Arsene Wenger has refused to rule out a move for former Arsenal captain Sol Campbell when the transfer window opens in January.
The former England defender has been training at the Gunners' Hertfordshire base since leaving Notts County.
The 35-year-old is free to resume his playing career after ending his contract dispute with the Coca-Cola League Two promotion hopefuls at the start of this month, and had been linked with Manchester United.
Sir Alex Ferguson earlier today ruled out the possibility of a move for Campbell, but it is something Wenger could consider.
Gunners boss Wenger feels there is still a strong bond between Campbell and the club he left for Portsmouth in the summer of 2006.
Wenger said: "I do not know yet, I have not really thought about that.
"At the moment, we have four centre-backs and we will always have four.
"If one would go, then I would consider it, but at the moment we are four, so I have no need to sign anybody else."
Wenger added: "I love Sol Campbell and the fact he came back here and wanted to practice with us shows he loves the club as well.
"You never say never in these kinds of situations."
The former Spurs and Portsmouth centre-back signed at Meadow Lane in August after being enticed to the club by director of football and former England boss Sven-Goran Eriksson - but left by "mutual consent" just one game into a lucrative five-year deal.
The Gunners boss insisted Campbell could still cut it at the highest level.
"Sol can still do a job in the Premier League, especially now he is fit. He has worked very hard," Wenger said.
