Oxlade-Chamberlain has played in a right wing-back role recently for Arsenal but is also capable of playing in central midfield and on the wing, and Henderson believes he will succeed in whatever position he is picked in.

"He also need to bring something to the table in order to get better, it's not only the manager".
"I am not naive enough to believe that".
