Morgan Schneiderlin limped off during Thursday's 2-1 Europa League loss to Lyon but is expected to be able to feature in the contest at Goodison Park this weekend. Let's hope the Gunners put that right on Sunday.
This season brings new territory for Arsenal as Wenger outlined how he has essentially made a decision to operate with two separate teams - one in the league and one for the cups.
"When you're questioned, in our job there is only one response and that is on the pitch".
"We have to deal with all kinds of speculation when the players are at the end of their contracts", he said. For the rest, we came out many times and said that's the situation. "When you play the next game, commit 100 per cent".
Arsenal provisional squad: Cech, Ospina, Mertesacker, Holding, Koscielny, Monreal, Debuchy, Bellerin, Nelson, Kolasinac, Maitland-Niles, Ramsey, Wilshere, Xhaka, Elneny, Coquelin, Ozil, Giroud, Walcott, Sanchez, Iwobi, Lacazette.
Koeman, meanwhile, has complete faith that the players he signed in the transfer window will get his side's season back on track.
"We need to take the situation for what it is now and prepare our team for Sunday".
There has been a red card in three of the last four Premier League meetings between these sides (Koscielny in May 2017, Jagielka in December 2016 and Gareth Barry in October 2015).
Everton have won just eight points this season; their worst start to a Premier League season through the first eight games since 2008-09 under David Moyes (also eight points).
