Arsène Wenger admits Sol Campbell was one of his finest ever signings as Arsenal manager.

The former Gunner announced his retirement from football on Wednesday after a career spanning almost 20 years - five of which were spent with Arsenal.

Campbell made almost 200 appearances in his first spell with the Club, before briefly returning in 2010 after spells with Portsmouth and Notts County.

“He was one of my best signings,” Wenger told Arsenal Player. “He was a guy I liked very much because he was fully committed and made a very difficult decision to join us in his career.

“Therefore I think we always have good relations with Sol here and when he came back I respected, like Thierry Henry, the effort he put in. His winning attitude was still the same when he came back and we have huge respect for him here.

“[We needed someone] who knew the Premier League at the time. We had an exceptional back four before and we got another exceptional one because people forget that Lauren, Kolo, Cole and Campbell were excellent.

“The question was how we could rebuild the back four but I think this one was absolutely exceptional.”
