#4 Unai Emery
Since his sacking at Arsenal, Unai Emery has maintained a relatively low profile and is without a job, despite being linked with a return to the Premier League. While the Toffees considered the Spaniard after sacking Marco Silva, they opted to make an ambitious approach for Carlo Ancelotti, a move that sensationally came to fruition.
Emery took over at Arsenal and replaced the legendary Arsene Wenger, who departed the club after the conclusion of the 2016-17 season. While the Gunners did not secure Champions League football in his first season at the club, they did, however, reach the final of the Europa League.
The seed for the Spaniard's eventual downfall in North London was sown in Baku, as Chelsea inflicted an embarrassing 4-1 defeat on the Gunners. Despite a summer of heavy spending, Arsenal started the season in underwhelming fashion and the hierarchy wasted no time in giving him the boot, as he was let go off midway through the season in favour of former club captain Mikel Arteta.
In his time in England, Emery's philosophy was criticized heavily and the English media were culprits in the sense that he was a bit of a laughing stock in the media, as his accent was mocked amongst other things. The former Paris Saint-Germain man is reportedly insistent on returning to the touchline next season but he might have to wait to do so, after two high profile failures in France and England.
