But Gunner boss Arsene Wenger believes there is nothing wrong with such attire - as long as it does not affect movement or vision.
He said: "I know there has been discussion of players using things like neck-warmers and leggings to keep warm, with Marouane Chamakh and Samir Nasri among the growing number of players wearing them.
"I have to explain, though, that both of them had stiff necks before the Aston Villa game - Samir could not train properly two days beforehand and it is a persistent problem for Marouane, so our medical staff were trying to protect them.
"I have no problem with it, as long as it does not restrict the players' movement or harm their vision."
