Arsenal currently sit third in the Premier League table, and whilst their Champions League destiny is well and truly in their hands, Arsene Wenger should walk if they fail to finish in the top four.
For too long now fans have grown used to missing out on the league title. Recent FA Cup successes have masked problems starting with Wenger and finishing with those doing his bidding on the pitch.
If Manchester United - or even West Ham - manage to stumble their way into the top four ahead of Arsenal, then changes must be wrung.

The Gunners' title charge has fallen apart in recent months. Embarrassing defeats to United at Old Trafford and Swansea City at the Emirates have allowed Leicester City and Tottenham Hotspur to embark on a two-way tussle for the prize.
Even before Sunday’s setback against Crystal Palace the league looked out of reach. Leicester's draw with West Ham had given them a brief flicker of hope, but it was extinguished as Alan Pardew’s side claimed a crucial point.
Arsenal's defence were to blame for the goal, but not the derailing of their season. Bottling it is a harsh term but considering the title will go elsewhere for a 12th consecutive year, it's the only one that can describe Wenger's squads in recent years.
Pep Guardiola arriving at Manchester City will change English football. Despite the fact they'll miss out on the Premier League title this season, their progress in the Champions League hints at a team ready to take their development to the next level.
And if Jose Mourinho becomes United manager, the Premier League will possess quite a managerial line-up. Jurgen Klopp has already worked wonders at Liverpool whilst Mauricio Pochettino has transformed Tottenham into a side capable of challenging for the country’s biggest honours.
Arsenal cannot afford to be left behind. Wenger has guided them to the top four every year since his arrival but failure to do so this year could - and perhaps should - prompt him to walk away.
Plenty of football is still to be played, and whilst a weight might have been lifted off Wenger's shoulders following his side's comfortable 2-0 win over West Brom on Thursday night, question marks remain over his head.
Splashing the cash this summer would go some way to appeasing Arsenal fans, but ultimately, Wenger's departure might be what they want most if the Gunners miss out on the Champions League.
