Former Everton manager Roberto Martinez has already been full of praise for the club's transfer target Amadou Onana.
The Blues have matched a bid from West Ham United for the Lille midfielder, which could potentially rise to £33.5m. Various reports over the last 24 hours have suggested the Blues are growing in confidence that the 20-year-old would prefer a move to Goodison Park over the London Stadium.
Onana was handed his debut for the Belgium national team back in June. He was introduced from the bench as the Red Devils lost 4-1 to the Netherlands in the Nations League and impressed Martinez, who has been in charge of Belgium since 2016.
