10 Most Expensive Transfer Flops In Everton History
10. Ramiro Funes Mori (£9.5m)
Everton played attractive, attacking football under Roberto Martinez, something that's in short supply at Goodison in 2017, unless the opposition are firing on all cylinders.
While blistering counters were the Spaniard's bread and butter, defensive frailty soon crept into his team's repertoire and the cracks in his backline only widened over time, until the Blues were shipping goals like nobody's business.
In a bid to steel up his rear guard, Martinez brought in Argentine defender Ramiro Funes Mori from River Plate in a deal worth £9.5 million. The leg-biting centre-half was hailed as the answer to Everton's defensive woes, but his presence largely exacerbated the problem in the long run.
Although Mori has never shied away from a tackle and even chipped in with a few goals during his debut season in blue and white, glaring errors hinted at the ugly part of the South American's game, and he eventually became just another part of the leaky defence that cost Martinez his job as head coach.
Under Ronald Koeman, Mori is no more than a squad player when he isn't battling long-term injury.
