It's now been three weeks since Koeman became the third Premier League casualty of the season - West Ham have since sacked Slaven Bilic - and yet the struggling club remain managerless.
The Toffees went into the season full of hope and optimism, having splashed the cash over the summer on players such as Jordan Pickford, Michael Keane, Gylfi Sigurdsson and Davy Klaassen, whilst they also brought Wayne Rooney back to the club.
In the immediate aftermath of Everton announcing their decision to part ways with Koeman, a number of big name managers were named as the leading candidates to replace the former Southampton boss on Merseyside. Silva nearly kept Hull City in the Premier League before leaving for Watford, who now lie ninth.
Before the global break, caretaker boss Unsworth claimed his first win in charge with a 3-2 victory over Watford, in which Everton came from 2-0 down to win 3-2.
Caretaker boss Unsworth has overseen four games so far, losing three, and he's likely to remain at the helm for the weekend's clash at Crystal Palace, who were the first top-flight team to change managers, switching Frank de Boer for Roy Hodgson.
The likes of Carlo Ancelotti, Chris Coleman, David Wagner, Sean Dyche, Sam Allardyce and even David Moyes were all touted as possible arrivals at the club.
