Mainz midfielder Jean Phillippe Gbamin is undergoing a medical at Everton.
Sky Sports says Gbamin is ready to make a move to the Premier League.
The 23-year-old is expected to replace Idrissa Gueye who left for PSG earlier this week for £29m.
The Merseyside outfit are flexing their financial muscles this week.
Along with the 23-year-old defensive midfielder, Everton are also signing striker Moise Kean from Juventus.
