Everton fans should be wary of the curse of Sam Allardyce

All of the Premier League clubs Allardyce has managed struggled after his departure - Blackburn Rovers, Bolton Wanderers, Crystal Palace, Newcastle United, Sunderland and West Ham United. If Allardyce does end up at Everton, Everton fans better hope he's a keeper.

Sam Allardyce could be set to return to Premier League management, with the 63-year-old the leading contender to take charge of Everton.

As reported by BBC Sport, Allardyce, who possesses a vast amount of experience of managing in the top flight, may soon be named as the successor to Ronald Koeman at Everton.

Allardyce isn't the most popular manager due to his alleged tendency to instruct his teams to play long-ball football, but Everton supporters could be forgiven for being fearful about his potential appointment.

There is evidence to suggest, however, that a curse of Allardyce does exists - in that each Premier League team that he manages ends up struggling following his departure.

Bolton Wanderers (1999-2007)

Allardyce's first venture into top flight management was at Bolton, with whom he achieved promotion to the top flight.

Bolton became a stable Premier League club under his guidance and also participated in the UEFA Cup.

However, since Allardyce's departure in 2007 Bolton have struggled. They ended up going to down to League One before being promoted to the Championship last season.

Newcastle United (2007-08)

Allardyce lasted less than a season at Newcastle following his appointment in 2007.

With ten defeats in his 24 games in charge, the Magpies struggled and Allardyce was dismissed. Newcastle were relegated at the end of the following season.

Blackburn Rovers (2008-2010)

The next step in Allardyce's managerial career came at Blackburn, whom he saved from relegation in 2008/09 after being appointed midway through the campaign.

Blackburn finished tenth the next season, but Allardyce was later sacked by controversial owners Blackburn Venky's.

Currently in League One, Blackburn fans have certainly found life difficult since Allardyce left.

West Ham United (2011-2015)

Allardyce helped West Ham to return to the Premier League in his first season in charge, but later received much criticism from the club's supporters for the team's style of play. Although West Ham thrived in Slaven Bilic's first season, last term was a disapointment - and events on this field this term were so bad that the club sacked Bilic for former Sunderland and Everton manager David Moyes.

Sunderland (2015-2016)

Another club whom Allardyce managed to save from relegation, with Sunderland surviving at the expense of rivals Newcastle United, who were relegated.

However, while Newcastle are back in the Premier League, Sunderland are in the Championship and are now in danger of relegation to League One. Sunderland's only hope appears to be new manager Chris Coleman.

Crystal Palace (2016-17)

Maintaining his reputation as being a specialist at preventing teams from being relegated, Allardyce helped Crystal Palace to preserve their Premier League status last season.

Now, though, Crystal Palace are bottom of the Premier League table, with relegation looking a strong possibility, notwithstanding recent performances under new manager Roy Hodgson.
