Everton forward Oumar Niasse has thanked former manager Ronald Koeman for resurrecting his career.
The striker said he was sorry to see the Dutchman get the sack after a tough start to the season.
Koeman dropped the Senegal forward ahead of the 2016-17 season after telling him he had no future at the club.
Niasse was then loaned to Hull City in January before being recalled for the current campaign.
