Arsenal manager Arsene Wenger won't rule out signing Sol Campbell on a free transfer after Manchester United played down talk of an Old Trafford switch for the former Gunners defender.
Campbell has been training with Arsenal since walking out on Notts County earlier this season after making just one appearance of the League Two club.
The 35-year-old is now able to resume his career following a contract wrangle with County, but a mooted move to the Premier League champions won't happen, according to United boss Sir Alex Ferguson.
Campbell has also been linked with Newcastle but there is also a slim chance of an emotional return to Arsenal, where he spent five years before joining Portsmouth in 2006.
"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," Wenger said on Friday.
Wenger's first choice centre-backs are currently William Gallas and Thomas Vermaelen, with Mikael Silvestre and Philippe Senderos as back-up. If any of those were to get injured, Wenger could be tempted to sign Campbell.
