On the October 24, 2015, Aston Villa made the bold decision to sack manager Tim Sherwood - a call which many earmark as the catalyst behind the club's downfall this season.
The Englishman was replaced by former Lyon boss Remi Garde, the appointment welcomed with open arms by the majority of Villa fans.
However, some six months later and the Frenchman was also shown the exit after failing to steer the Villains out of the relegation zone. Their imminent drop was confirmed earlier this month.

Ultimately, the biggest mistake Villa made en route to being relegated for the first time since 1987 was letting Sherwood go, simply because of the passion and desire to succeed he showed on a weekly basis.
At a club like Villa, what fans want most is a manager and squad of players willing to give their all every game, and under Garde, they showed very little commitment to the cause.
Prior to his departure, Sherwood had seen victory in just one in ten Premier League games. Results are everything, of course, but the fight shown during a 3-2 defeat to Liverpool and 2-2 draw with Sunderland was exactly the kind needed to avoid relegation.
Sure, desire might not have been enough in the end, but it would have given them a far better chance compared to their abysmal performances under Garde.
Villa now face a battle to restore Premier League status, and it's without question that they need to appoint a big name capable of controlling the egos that remain in their squad.
An authoritative figure like Nigel Pearson would be ideal, the former Leicester City boss famed for his hard-headed approach to management.
David Moyes, on the other hand, hasn't the credentials to manage in the Championship.
You need look no further than the plights of Fulham, Bolton and Blackburn - who were all relegated from the Premier League and have since struggled - as evidence of how detrimental poor managerial appointments can be. They now face a battle to avoid the drop into League One.
One way or another, an important summer awaits Aston Villa Football Club, but they must learn from the mistake of letting go a manager who was willing to fight until the very end.
