Campbell included in Newcastle squad for Anzhi tie
Campbell is now fully recovered from a knee injury and hoping to add to his debut appearance in Europe against Atromitos.
Of seeing Samuel Eto'o in action, he told the Evening Chronicle: "He's one of the most high-profile players out there when you look at the clubs he's had and records he's got.
"He'd be a great chance to just sit and watch him play to see his movement and how he uses his speed.
"I've always been a fan of his so it will be good."
