Top 5 managerial sackings of 2017

#2 Ronald Koeman

Koeman spent heavily in the transfer window but didn’t get his squad balance right

The Dutch footballer is considered one of the best defenders of his generation, being a part of Johan Cruyff's "Dream Team". He had an illustrious career as a player, being one of Europe's five players ever to win a treble at their club and a cup with their national team in the same year.

As a manager, he had successful spells in Spain, Portugal, the Netherlands and England, having coached the likes of PSV, AFC Ajax, Feyenoord, Valencia, Benfica and Southampton. In the 2015-16 season, he masterminded Southampton's highest ever Premier League finish in sixth place and earned qualification for the group stage of the Europa League.

This got him the job at Everton in June 2016. In his first season, Koeman led Everton to the Europa League. The club then spent an estimated £150 million on new players under in the summer of 2017, with the likes of Gylfi Sigurdsson, Jordan Pickford and Michael Keane signing for record-breaking fees.

However, his inability to replace Romelu Lukaku up front and to get his signings playing at their best, cost the club, as they slipped into the relegation zone. Koeman was sacked on 23 October 2017, following a 5–2 home defeat against rivals Arsenal.
