With Arsenal's faint title hopes all-but-extinguished following their drab 1-1 draw with struggling Crystal Palace on Sunday, manager Arsene Wenger's future at the club has been thrown into further doubt.
The Frenchman has spent almost 20 years with the Gunners since being appointed in October 1996 and, despite substantial financial backing, has only won three Premier League titles and six FA Cups.
Performances in the Champions League over the past few seasons have left a lot to be desired, while Arsenal's inability to mount a serious title challenge has resulted in a selection of supporters becoming disillusioned with Wenger's style of play.

But who should the Gunners' board appoint if they decide to part ways with Wenger this summer? Here's five potential candidates.
One of the best young managers in Europe, Simeone is worshipped at Atletico Madrid.

His side is well drilled defensively and lethal going forward, whilst the Argentine's balanced approach to the game would be well-suited to the Premier League.
In addition, Simeone is passionate and entertaining on the touchline - apart from success, what more could Arsenal fans want from a manager?
Despite only being 45, Simeone is vastly experienced in the Champions League. He took Atleti to the 2014 final, where they were seconds away from victory over rivals Real Madrid, and won La Liga during the same season.
Antoine Griezmann and co. are currently second in the league and level on points with Barcelona following the Catalans' recent run of disastrous form, and could end the campaign as champions once more.
A proven manager in the Premier League and Champions League, Pellegrini would make a seamless transition to Arsenal's dynamic, attacking style of football.
The 62-year-old will make way for Pep Guardiola at Manchester City this summer and has stated his desire to remain in England - could north London be a potential destination?
Arsenal's squad only needs a few tweaks here and there and with the possibility of financial backing from the board, Pellegrini could bring in the right players to help the Gunners compete for the title once again.
Three trophies in three seasons at the Etihad is a respectable return for the former Real Madrid manager and he could yet add a Champions League triumph to his CV.
Blanc has exceeded expectations at Paris Saint-Germain with three consecutive Ligue 1 titles, but progress in Europe has been a major disappointment for Qatar Sports Investments.
However, with an array of talent on display at the Emirates and a hefty war chest, the Frenchman may find a move to north London tempting should Arsenal come knocking.
The Premier League would certainly offer a greater challenge to Blanc given the ease in which PSG have won the Ligue 1 title this season.
Competing alongside the likes of Chelsea, former employers Manchester United, City and Tottenham Hotspur would represent an exciting prospect for Blanc.
The former Roma manager is out of a job at the moment but reinvigorated the Italian giants during his three-year stay in the capital.
The Frenchman also masterminded Lille's 2010/11 Ligue 1 title triumph with Adil Rami, Eden Hazard, Gervinho and Moussa Sow flourishing under his guidance.
Garcia finished as Serie A runner-up twice with Roma before eventually being sacked midway through the current campaign.
At 52-years-old, Garcia still has his best managerial years ahead of him and would bring an exciting brand of football with him to north London should he be approached.
A highly sought-after manager, Allegri rose to prominence in Italy with Sassuolo before moving to Cagliari and then AC Milan.
Now with Juventus after winning the Serie A title last season, the Italian is renowned for his ability to adapt tactically during a game and swing the tie in his side's favour.
It's unlikely that Allegri will become available this summer, but should the opportunity arise, Arsenal would be mad not to approach one of Europe's most exciting managerial prospects.
