The WBC cruiserweight champion and Toffees fan did not hide his admiration for the Dutchman and hopes his club manage to keep hold of him
Boxing champion Tony Bellew has warned Barcelona to "keep away" from Everton boss Ronald Koeman in their search for a successor to Luis Enrique.
The Barca coach announced his decision to leave at the end of the season on Wednesday, opening up a vacancy at one of the biggest clubs in world football.
Koeman is among the frontrunners to take the reins at Camp Nou, having spent six years at the club as a player, winning four La Liga titles and the European Cup.
