Speaking in his column with the Daily Mail, Carragher said: “For those three players, every season their story has been the same: they will have a few good games, then pick up an injury, be in and out of the side, and their form ends up tailing off before all goes quiet.
“I still don't know what Oxlade-Chamberlain's best position is. Is he a centre midfielder or a wide man? He has started the season well but can he sustain it?
“As for Walcott, he is in the ludicrous position of wanting to be considered as a wide player even though Arsene Wenger was talking him up in the summer as being a striker.
“It can't keep happening."
