The Senegal international arrived at Goodison Park from Lokomotiv Moscow for £13.5m in January, the third largest fee paid in Toffees history, but barely featured in the second half of the 2015/16 campaign.
Despite not having been listed as injured by the club, Niasse has played in just 45 minutes of a behind-closed-doors friendly during pre-season, not even featuring in the squads for subsequent non-competitive fixtures against Barnsley and MK Dons.
Should he disappear back into the relative obscurity from which he came, having barely grazed the first-team despite his sizeable fee the 26-year-old is a dead cert for a place in the pantheon of the Premier League’s worst ever minutes per million signings, a niche already occupied by the following misguided acquisitions.
United paid £7.5m for a forward whose sole previous season in a European top flight had seen him notch four times in 26 games for Portuguese side Estrela Amadora.
The fact that he arrived via a five-month spell at Vitoria Guimaraes, during which he didn’t play a game, only heightened the sense that there might have been more to the deal than met the eye.
He played just seven times for the club across four seasons, for a total of 335 minutes, but the two goals he bagged during that period actually set him apart from the his peers in this article in a positive fashion.
A Croatian international before his arrival at Aston Villa, Balaban’s spell in the second city is memorable purely for how abject a failure the £5.8m switch was.
He played 175 minutes split across nine outings for the Villans in 2001/02 without finding the net, a fact made all the more galling as he had bagged 14 in 27 league games the season before at Dinamo Zagreb.
Loaned back to his former employers after one campaign, he promptly began finding the net at an even better rate (15 strikes in 27 matches). When he left Villa having had his contract terminated in 2003, he joined Club Brugge where he netted 40 times in 83 divisional outings.
Looking a left-field signing in the extreme when plucked from Serie B Brescia for a fee reported to be as much as £9m by West Ham in 2009, Savio preserved the sense of mystery surrounding the deal by mustering a total of 261 minutes across 11 showings for the club.
Failing to score during that period, he was sold on to Fiorentina at a substantial loss, beginning a ten-club spell of journemanning taking in Italy, Germany, Romania, Kazakhstan, Bulgaria and Lithuania, notching the sum total of one league goal along the way.
Vicente Matías Vuoso
Given he’d bagged a relatively modest 14 times in 66 league games for an Independiente side also boasting the far more conspicuous talents of Diego Forlan, Vuoso’s acquisition by Manchester City in 2002 for a fee thought to be higher than £6m by transfermarkt.com was an eyebrow-raiser.
He failed to make a single competitive outing for City and was loaned out to Mexican side Santos Laguna the very next season.
