Those are the words of Wenger. It's as if no-one highlighted this issue during the summer, isn't it? Wenger's stance over contracts has not paid off, and he's right in acknowledging that all is not well at the Emirates Stadium. However, with Walcott gone, Sanchez almost gone and Wilshere and Ozil said to be close to signing new deals, maybe it will only be a matter of days or weeks before everything settles down.
Those are the words of Hodgson, who is able to head into the game without being overly concerned about the results of the teams in and around Palace. The club are still only five points above the relegation zone but given that the Eagles have previously been a couple of wins from safety, it's a new feeling ahead of their trip to North London.
ARSENAL XI: Cech; Bellerin, Mustafi, Koscielny, Monreal; Elneny, Xhaka; Ozil, Wilshere, Iwobi; Lacazette
