Read more quotes from Arsene Wenger ahead of Saturday's Premier League opener against Crystal Palace:

on Mikel Arteta's contract...He is a strong personality, Mikel Arteta. I don’t really doubt that he will extend his contract but at the moment it is not done.on Nacho Monreal at centre back...He can [do well there], yes, because he is intelligent, because he has a good sense of interception. Because he reads the game well and because he is a good passer of the ball and for us it is important coming out from the back. [Opponents] drop off at home so we need very good passing out from the back.
