Mikel Arteta was appointed as Arsenal head coach on Friday. Here are five issues he must address quickly.
Sort out the defence
Speak to any Arsenal supporter and they will tell you the first thing any new manager needs to fix is the defence - the team have not kept a clean sheet for 14 games.
Long gone are the days when they could rely on Lee Dixon, Tony Adams, Steve Bould and Nigel Winterburn to keep clean sheets for fun.
Arteta must get his team defending as a unit again and he has to find an effective centre-back partnership.
Sokratis playing alongside Calum Chambers does not look like the answer and he needs to decide if he wants summer signing David Luiz back in the team. Arteta will also have to deal with the fact both first-choice full-backs - Hector Bellerin and Kieran Tierney - are out injured.
What do you do with a player like Mesut Ozil? There is no denying his ability but many Arsenal fans think he is a luxury the club can no longer afford.
You can imagine him thriving in a winning team where he has the freedom to express himself but he does not look like what Arsenal need at the moment.
Ozil was clearly unhappy when he was replaced by Emile Smith Rowe after less than an hour of the 3-0 home defeat against Manchester City on Sunday. Freddie Ljungberg explained the substitution by saying he needed more energy in the team.
As a former Arsenal captain, Arteta knows what it means to lead the side on the pitch.
The saga surrounding the captaincy has been symptomatic of the problems at the club since Arsene Wenger left 18 months ago.
Unai Emery allowed the players to vote for the captain in the summer and their choice of Xhaka was always going to create problems with fans who are not convinced the Switzerland midfielder is good enough to be playing for Arsenal.
Xhaka was stripped of the captaincy after he reacted badly to being booed by his own fans when he was substituted during the draw with Crystal Palace in October.
Emery made Pierre-Emerick Aubameyang captain instead but many Arsenal fans are not convinced the striker is captaincy material.
Arteta must decide whether to persist with Aubameyang or put a new man in charge.
Get the best out of Lacazette
On his day Alexandre Lacazette is one of the best strikers in the Premier League but he looks totally disillusioned with life at Arsenal at the moment.
He looked cold and miserable on the bench against City on Sunday as young players such as Smith Rowe, Bukayo Saka and Willock were sent on instead of him.
Arteta needs to find a way of getting Lacazette and Aubameyang back together in Arsenal's starting XI. Lacazette is too good a player to be sitting on the bench.
His contract runs out in the summer of 2022 but unless he returns to being an automatic starter, it is difficult to see him wanting to stay at the club for long.
Get back into the top four
Arsenal's main focus has to be getting back into the Champions League.
Unless results improve immediately, Arsenal will miss out on playing in the Champions League for a fourth season in a row.
