Amadou Onana is due to undergo a medical at Everton, the ECHO understands.
The 20-year-old has agreed personal terms after the Blues swooped for him this week, reaching a deal thought to be worth in excess of £30m with French side Lille. He had been on the club's radar for some time but the Blues swooped for the Belgium international this week while West Ham United were in talks for his signature.
The midfielder is set to be a key part of Frank Lampard's efforts to strengthen his squad. Talks to seal Idrissa Gueye's return to Goodison Park from Paris St Germain are also ongoing. The 32-year-old has been left out of PSG's squad to face Clermont this weekend.
