Unai Emery and Arsenal have a big week ahead of them.
After a good start to the season, they were undone by Liverpool at Anfield on Saturday.
And the one game no fan wants to lose is coming up this weekend - the North London Derby.
There could be some players leaving the squad before that match comes around, while Emery has a number of team selection issue to sort out, too.
Here are the biggest Arsenal stories from the past 24 hours.
David Luiz question
If David Luiz is the answer, what is the question?
That's extremely harsh on the man who has won plenty of silverware in his career, but it may be a question that many Arsenal fans are asking themselves.
Luiz was a shock deadline day signing from Chelsea, but his Arsenal career has not exactly got off to the best start.
The Brazilian was at fault for two Liverpool goals during the 3-1 defeat at Anfield on Saturday.
Aubameyang's cryptic message
Pierre-Emerick Aubameyang was without his mate on Saturday.
Alexandre Lacazette started on the bench, although he did make an appearance in the second half, for nine minutes.
With Nicolas Pepe arriving at the club this summer, will Emery play a front three, or will someone miss out?
Aubameyang has a good friendship with Lacazette, and the Gabon striker was asked about the Frenchman's role in the team and specifically why he is left out by Emery on occasion.
This is what Aubameyang had to say.
Nacho Monreal latest
Unai Emery is still hoping to let a few players leave before the end of the European transfer window.
Teams in Italy, France, Germany and Spain can all sign players from England until September 2.
And Nacho Monreal looks likely to be one heading for the exit.
Here's what we know about his future.
Power rankings
After defeat to Liverpool, no one will come out with flying colours will they?
