Everton have signed Belgium midfielder Amadou Onana from Lille for £33m.
The 20-year-old was at Goodison Park on Saturday to watch Everton's 1-0 defeat by Chelsea in their opening Premier League game of the season.
West Ham were also interested in Onana and had agreed a fee for the player.
"It feels great to join Everton," he said. "I know it's a big, big club, one of the biggest in England. It's something I want to be part of for many years."
Onana becomes Everton's fifth signing of the summer after James Tarkowski, Dwight McNeil and loan pair Ruben Vinagre and Conor Coady.
