​Everton's big-money flop Oumar Niasse looks set to be leaving the club just seven months after arriving, with Turkish side Galatasaray keen to bring the player in on loan next season.

According to Turkish news outlet ​Fotomac, the Senegal international will be offloaded by the Merseyside club, despite costing them £13.5m to bring the player in January under former manager Roberto Martinez, making the player the club's third most expensive signing.

New manager Ronald Koeman hasn't been at the club long, but has already told the former Lokomotiv Moscow player that he is surplus to requirements, and Galatasaray appear keen to bring the player to the Super Lig on loan. 

This will cost them £1.5m, however, negotiations are currently falling flat with the Turkish giants' proposal to pay £5m the following season should they want the Senegalese striker on a permanent basis.

Everton appear reluctant to agree to this term due to the amount of money they would lose on the player following their purchase of Niasse in January 2016 for more than double that figure.

Niasse only made seven appearances for the Toffees, and failed to find the net once in his first experience of Premier League football, however Galatasaray will be boosted with the knowledge that the 26-year-old has already played in Turkey before in 2013, where he scored 15 goals in 40 outings for Akhisar Belediyespor.

Roberto Martinez, the man who brought Niasse to the club before being sacked the following May, is reportedly in line to jump straight back in to the managerial hot seat with the recently vacated position at Hull City, following Steve Bruce's sudden resignation, and remains the front-runner for the job.
