Arsène Wenger believes Sol Campbell has the qualities to become a successful football coach.

The former Arsenal defender is in the news again after walking out on Notts County just one game into his fledgling League Two career. Campbell followed Sven Goran Eriksson to Meadow Lane last month as County's ambitious new owners flexed their financial muscles, but the 35-year-old could only muster 90 minutes at Morecambe before leaving the club by mutual consent.

Campbell's departure left Eriksson "disappointed" and prompted questions about the former England star's mental fortitude. But Wenger has defended his old centre back, insisting that Campbell has the strength of character to move into a coaching role.

"Sol is a strong man," said Wenger. "When he has his mind on something he goes for it, but he needs a real target.

"One advantage of our job is that you learn a lot about the complexity of human beings. We are all complex. They're young people, between 20 and 30 is a sensitive age, anything can happen at that age.

"There is a moment in football, and in any job, where you have to know how far can you go to be responsible because it's a job. Where does the private life come in and where does the respect of his life come in? It's difficult."
