Campbell is set to ink a six-month deal with the Gunners.
"I've seen the young players in training, they are fantastic, great players," said Campbell, who has worked tirelessly at Arsenal's London Colney headquarters for the past few months, since his departure from Notts County in September.
"It's fantastic being a great player but, as the games comes thick and fast and when you've got to get a win here or get a draw and it's the fifth game or whatever and everyone's tired, it's just dragging the lads over the line and getting a result. Because those points all add up.
"The likes of me and William [Gallas], they've seen it all before, and Cesc [Fábregas]; that's what it's all about ... showing when you've got that green light, it's just to keep it going, really."
