2. Ronald Koeman
Koeman got the job at Everton in June 2016. In his first season, he led Everton to the Europa League. 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.
1. Carlo Ancelotti
Ancelotti appointed the manager of Bayern Munich in 2016, was to continue their domestic dominance and break the grip that the Spanish teams had in Europe. The club hasn’t won the Champions League since 2013 and doing so wasn’t easy.
While his union with Bayern seemed perfect when he joined in 2016, the lack of silverware apart from the Bundesliga title in his first season put pressure on him to perform better the following season.
With multiple losses in the league and the Champions League, Ancelotti was sacked on 28 September 2017, due to creative differences. It was also reported that he had lost the dressing room.
