Vermaelen happy learning from Arsenal veterans Campbell, Gallas
"For me it does not matter," Vermaelen told arsenal.com. "I have played with all three centre-backs and for me it doesn't matter, it is the boss' decision.
"William trained today and I think he will be in the squad tomorrow. For me it does not matter who plays."
Campbell and Gallas are favourites to line up alongside Vermaelen and the 24-year-old Belgian rates them both.
"There is a difference," said Vermaelen. "But they are both really experienced and that helps me a lot. They are both really good players and it is good for me to play alongside these two players."
