It's been tough old season for Everton after a summer of optimism, with the club in bottom three of the Premier League after nine rounds of games.Sunday's 5-2 loss to Arsenal was the final straw for the Toffees board as they announced on Monday afternoon that they had parted ways with manager Ronald Koeman.It is a sad end for the Dutch coach who guided the club to seventh place last season, but in truth, the former Southampton boss needed to go.A statement said the club "would like to express their gratitude to Ronald for the service he has given to the club over the past 16 months".Everton spent a lot of money on the likes of Jordan Pickford, Michael Keane and Gylfi Sigurdsson but have failed to look like a half decent team all season."I still believe I can change the whole situation," was what Koeman said on Sunday after the crushing defeat by Arsenal, but clearly, the men upstairs thought he couldn't.Now, Everton face the task of finding his replacement, something which certainly will not be easy in the current managerial climate.Burnley's Sean Dyche has been mentioned, while Wales boss Chris Coleman and former Toffees man David Moyes are among the favourites.Twitter, of course, reacted to the huge news of yet another managerial casualty and Sky Sports pundit Jamie Carragher had one of the best.

CARRAGHER REACTS

Some of the replies to the tweet were also brilliant, with Gary Neville being brought up a few times.

To be fair, Ryan Giggs has always expressed his desire to go into management and famously took charge of Manchester United for a few games after Moyes was sacked.

Of course, the tweet is referring to the famous Andy Tate reaction videos during Moyes' disastrous time at Old Trafford but still, it could be a viable option.

It is set to be a testing few days for Everton, with a massive game against Leicester in the league just on the horizon.

Should they lose to the Foxes, they face the very real prospect of being dragged into a relegation battle. Scary times at Halloween for the Toffees.
