Chelsea boss Antonio Conte and West Ham manager Slaven Bilic among the favourites in the Premier League sack race after departure of Ronald Koeman
- Everton became the third Premier League club to sack their manager this season
- Ronald Koeman was given the boot after 16 months in charge at Goodison Park
- West Ham boss Slaven Bilic is the bookmakers' favourite to leave his job next
- Antonio Conte, Mark Hughes and Tony Pulis also find themselves under pressure
Less than three months into the Premier League season and already three top-flight managers have been relieved of their duties.
Ronald Koeman followed in the footsteps of Craig Shakespeare and Frank de Boer on Monday as Everton gave him the boot after just 16 months in charge.
Leicester are close to appointing former Southampton boss Claude Puel as their new manager after Shakespeare's departure, while Crystal Palace now have Roy Hodgson in charge after dispensing of De Boer's services after just four games.

But it appears likely that more clubs will be in Everton's position in the coming months, with a number of big-name bosses increasingly under pressure.
Slaven Bilic is odds-on to be sacked by West Ham, while Antonio Conte's position at Chelsea remains under threat after a mixed start to the season.
Here, Sportsmail takes a closer look at the six managers who are most in danger of losing their jobs according to the bookmakers.
..................................................................
Slaven Bilic (West Ham)
Odds to be the next Premier League manager to leave: 4/6
Bilic is the overwhelming favourite to be the next manager to lose his job following the sacking of Koeman and Friday's disastrous 3-0 home defeat by Brighton.
That result left the Hammers 16th in the table and out of the relegation zone on goal difference only, with a trip to fellow strugglers Crystal Palace next up after Wednesday's Carabao Cup tie against London rivals Tottenham at Wembley.
West Ham are believed to be lining up a move for Hoffeinheim's promising young boss Julian Nagelsmann, while former Borussia Dortmund manager Thomas Tuchel is also under consideration to replace Bilic.

Mark Hughes (Stoke City)
Odds to be the next Premier League manager to leave: 9/1
Hughes retains the support of Stoke chairman Peter Coates despite Saturday's 2-1 home defeat by Bournemouth, but the former Manchester City boss is under no illusions about the need to improve results fast.
The Potters find themselves 17th in the table and only out of the drop zone on goal difference ahead a tough trip to in-form Watford on Saturday afternoon.
Hughes led Stoke to ninth-place finishes in his first three seasons in charge, but last term's 13th has increased concern among some supporters.

Antonio Conte (Chelsea)
Odds to be the next Premier League manager to leave: 11/1
After a turbulent summer in which Chelsea failed to land a number of their top targets, Conte needed to hit the ground running. Instead, he began with a home defeat by Burnley.
Since that day in August the Italian has steadied the ship, although the recent loss at rock-bottom Crystal Palace has led to more questions over his future.
With the Blues nine points behind leaders Manchester City and seemingly in a battle for a top-four spot, the pressure is on Conte to deliver the sort of results and performances which made Chelsea champions during his debut season in England.

Mauricio Pellegrino
Odds to be the next Premier League manager to leave: 12/1
Pellegrino has only been in charge at St Mary's since the summer, but he already finds himself among the favourites for the sack after an up-and-down start to life on the south coast.
Saturday's narrow victory over West Brom has eased the pressure on the Argentine, although Southampton's lack of goals remains a concern.
Saints are 10th in the table after winning three, drawing three and losing three so far, but the sacking of Puel, who finished eighth and reached a cup final last season, shows that the club's hierarchy expect improvement.

Paul Clement (Swansea City)
Odds to be the next Premier League manager to leave: 18/1
Clement proved his worth after arriving at Swansea in January, helping them avoid relegation to the Championship with a game to spare.
But a poor start to the season, which has seen the Swans lose five of their nine top-flight games so far, has left the former Bayern Munich assistant in an uncomfortable position.
The loss of Gylfi Sigurdsson has been felt, while summer signings Renato Sanches and Wilfried Bony have failed to impress. And next up is a trip to Arsenal...

Tony Pulis (West Brom)
Odds to be the next Premier League manager to leave: 18/1
After starting the season with back-to-back 1-0 wins over Bournemouth and Burnley, things have quickly gone downhill for Pulis and West Brom.
Saturday's defeat at Southampton left the Baggies 13th in the table and without a victory since the win at Turf Moor on August 19.
Pulis' style of play has been tolerated by fans when results have been good, but it is likely to become a talking point again if this current run of poor form continues.
