sport news Everton's £500m mistake: The full scale of the transfer disasters under Farhad ...

For all the talk of clubs spending big, Everton's transfer dealings sometimes go slightly under the radar in comparison to those of Arsenal, the Manchester clubs or Merseyside neighbours Liverpool.

The arrival of Farhad Moshiri as owner in February 2016 saw the replacement of Roberto Martinez with Ronald Koeman and record amounts of cash thrown at the team in pursuit of success. 

Martinez had come off the back of two underwhelming 11th-placed league finishes, with the biggest shining light coming in the form of Romelu Lukaku's goals following the Belgian's club-record £28million move from Chelsea in 2014 following a very fruitful loan campaign at Goodison Park. 

Moshiri was not shy about setting his sights high as he let Martinez know that Champions League football is what he should strive for, while the Monaco-based businessman planned for a director of football to turn the side from mid-table also-rans to one of the Premier League's big hitters.

The man who filled that director of football role that summer was Steve Walsh, who had moved from Leicester City, where he had scouted the likes of Jamie Vardy, Riyad Mahrez and N'Golo Kante. 

The bargain trio, under the stewardship of Claudio Ranieri, helped guide the Foxes to the most improbable title triumph of all time as the Midlands outfit stunned England with an exciting, counter-attacking style.

The move was seen as a coup by the club and after Walsh's arrival they spent over £80million in their first campaign - a club record - on Idrissa Gueye, Ashley Williams, Yannick Bolasie, Dominic Calvert-Lewin, Ademola Lookman and Morgan Schneiderlin.

Of those, only Calvert-Lewin is still at the club, with the Sheffield-born striker's career blossoming once Carlo Ancelotti joined in December 2019.

A succession of injuries and poor form meant £24m Schneiderlin's attempt to revive his career under his old Southampton boss following a terrible spell at Manchester United did not go as planned.

The £30m shelled out on the skilful but inconsistent Bolasie, meanwhile, yielded just 32 appearances, two goals and four assists - in part due to a serious knee injury that kept him out for a year - before a series of loan moves then led to a permanent transfer to Turkey this summer after his contract expired. 

Lookman wasn't able to live up to the promise that he showed when he netted on his debut as a teenager in a 4-0 win over Manchester City in January 2017. 

Having shone in a Swansea side that punched above their weight, £9m Williams continued to impress during his first season in the North West. 

However, the following term saw Everton let in 58 goals - with only four sides posting a worse record. The Wales international subsequently joined Bristol City after being released. 

Only Gueye could be considered a success alongside the £1.5m Calvert-Lewin, but the talented midfielder was tempted away from England by an offer from Paris Saint-Germain in 2019 just after winning the club's Players' Player of the Season award along with Lucas Digne. Gueye joined the French giants for £30m - a rare handsome profit.

The 2016-17 season saw a seventh-place finish, which was a marked improvement on the previous two years and something resembling the fifth place that Martinez secured in 2014 that had the club dreaming of regular European football.

If the previous season had seemed excessive in spending terms, 2017-18 was going to provide a whole new definition for the word as the team stagnated, finishing eighth and crashing out of the Europa League at the group stage as both Koeman and his replacement Sam Allardyce were relieved of their duties.

Roughly £175m was spent on 13 players across two transfer windows, including big-money buys Nikola Vlasic (£8m), Theo Walcott (£20m), Davy Klaassen (£24m), Jordan Pickford (£30m), Michael Keane (£30m), Cenk Tosun (£27m) and Gylfi Sigurdsson (£45m).

Koeman lamented that the loss of Lukaku and the failure to replace him with Olivier Giroud cost him his job, with other mainstays like Ross Barkley and Gareth Barry also leaving that summer.

Vlasic moved from Hajduk Split before joining CSKA Moscow for £14m in 2019 having scored just two goals in all competitions. 

Much as Arsenal fans were frustrated and thrilled in equal measure by Walcott's displays, the Everton faithful rarely got to see the winger perform well on a regular basis as he produced just 11 goals and nine assists in 85 games. 

Klaassen failed to score in 16 games before leaving for Werder Bremen for barely half his previous fee, while Tosun's time in England has been ravaged by two major knee injuries, the latest of which still keeping him on the sidelines since April.

Keane and Pickford's careers are harder to judge. Both men have featured regularly since arriving in the summer of 2017, but the pair have each experienced significant spells of poor form, while Everton finished in the bottom half of the table on goals conceded during two seasons (2017-18 and 2019-20).

Despite a standout 2018-19 in which he scored 13 league goals, assisted a further six and played in every game, Sigurdsson, like Williams, has failed to hit the heights he reached at Swansea.

The summer of 2018 could be looked on as Everton's most successful, with Marcel Brands succeeding Walsh after a torrid summer as Marco Silva took the reins, with the Dutchman sharpening the club's transfer approach and focusing on youth as they spent a mere £90m on Richarlison, Yerry Mina and Digne.

Richarlison finished joint-top scorer in his first two seasons and although his output dropped last season, his link-up play and work rate mean he has a good chance of returning to double figures for goals under Rafael Benitez.

Digne has established himself as the club's first-choice left back and has arguably been the most consistent performer since his arrival, while Mina has been in and out of the side.

However, another eighth-place finish was disappointing and so another
