Massimiliano Allegri? Luis Enrique? Mikel Arteta? Talk of Arsene Wenger's successor is rife as the Frenchman prepares to take charge of his final game as Arsenal manager on Sunday against Huddersfield Town, but what exactly is he leaving behind?
Wenger has always said he would leave the team in a good state when it came to his departure, and this week he argued that he has fulfilled that promise. "The squad doesn't need much, because there's a huge potential there," he said. "There's a good spirit. A good basis. It needs two or three additions and this team will compete for the championship next year."
Wenger's assessment was typically optimistic, but the Premier League table paints a different picture. As things stand, Arsenal are 12 points off the Champions League places and 37 points off champions Manchester City. They are already guaranteed the lowest Premier League finish and lowest points total of Wenger's tenure.
Recent form has been far from convincing and meetings with their top-six rivals have done little to suggest Arsenal are as close to mounting a title challenge as Wenger suggests. This season, their record against Manchester City, Manchester United, Tottenham, Liverpool and Chelsea reads: P10 W1 D3 L6. They have conceded nearly twice as many goals as they have scored in those games.
The FA Cup has offered respite in previous campaigns, with Arsenal overcoming City and Chelsea on their way to lifting the trophy last year, but this season the cup competitions have only accentuated the issues. Arsenal were embarrassed by Manchester City in the Carabao Cup final and outsmarted by Atletico Madrid in the Europa League semis.
Their ongoing struggles against top opposition point to a lack of mental resilience and leadership on the pitch - issues which have also been highlighted by their seven-game losing streak in Premier League away games since the turn of the year - and they also expose the holes in Wenger's squad.
The question marks start in goal, where the soon-to-be 36 Petr Cech no longer provides the same level of security as he once did, and David Ospina remains an unconvincing alternative. A new goalkeeper should be a priority in the summer but the need is perhaps even greater in defence.
The centre-back position has been problematic for over a decade for Arsenal and it remains that way today. Laurent Koscielny will be 33 by the time he returns from his Achilles injury next season, while Shkodran Mustafi's frequent lapses of concentration suggest he is not the man to build around.
At full-back, Wenger's successor must also consider whether Sead Kolasinac is capable of producing defensive work to match his attacking output, and whether Hector Bellerin has plateaued or whether he simply requires more attention on the training field.
There is uncertainty in midfield too. Granit Xhaka has not missed a single Premier League game this season but continues to attract criticism, while Aaron Ramsey and Jack Wilshere remain worryingly prone to injuries and Mesut Ozil's inconsistency is as apparent as ever. With Santi Cazorla also heading towards the exit, Arsenal are crying out for reinforcements.
Their collective issues are just as troubling. In recent years, Arsenal have become error-prone and tactically naive. According to Opta, they have made more errors leading to shots (31) and goals (15) than any other Premier League side in the current campaign. It is a worrying statistic which underlines the size of the task facing Wenger's successor.
That is not to say there are no tools to work with.
Arsenal have shown they are still capable of playing devastating attacking football in their recent wins at the Emirates Stadium - not least Sunday's 5-0 thrashing of Burnley. Over the course of the campaign, only Manchester City have scored more home goals than Arsenal in the Premier League.
Up front, club-record signing Pierre-Emerick Aubameyang has given them a genuinely elite option. His first 12 Premier League games have yielded nine and four assists, and Arsenal will also be encouraged by how he has combined with Alexandre Lacazette.
There is young talent as well. The 20-year-old Ainsley Maitland-Niles was named man-of-the-the-match in Arsenal's late defeat to Manchester United last month and he isn't the only youngster to have impressed lately. Konstantinos Mavropanos's sending off at Leicester came after hugely encouraging displays against United and Burnley, while Reiss Nelson and Joe Willock have been similarly impressive.
It will be down to Arsenal's next manager to ensure that those young players are given chances to continue their development in the seasons ahead, but it is down to the club to ensure that the squad is bolstered with more experienced reinforcements too. Only then will the task at hand begin to look a little less daunting for Wenger's successor.
