VIDEO: 'That's the secret' - Leny Yoro given advice on how to succeed at Man Utd by club legend Rio Ferdinand after completing transfer from Lille

Lille and Manchester United completed a £52 million ($68m) deal for the transfer of Yoro and the Red Devils made his announcement official with the Frenchman receiving a video message from Ferdinand, who advised the 18-year-old on how to succeed with the club.

On the video message for Yoro, the United legend said: "Leny, Leny, Leny, how you doing bro? Listen, congratulations. Welcome to Manchester United man. I wish you all the best. I know you're going to work hard, and that's the secret, man. Work hard. Work hard. Work, work, work on all your parts of the game.

"You've got all the potential. You've got all the tools, man. You've got everything there. Ready to rock and roll to make a big impact at this club. It's the best club in the world. It's a beautiful place to be in. Go and enjoy yourself, man. I'll see you soon. Good luck. Let's go. Let's go. Let's go. Leny, Leny, Leny."

If specific athletic goals are reached, the fee United pay Lille might increase to £60m ($78m). Yoro, who has made 60 appearances for Lille, has inked a five-year contract with the Premier League side through 2029. Lille finished fourth last season and the 18-year-old centre-back was named in the team of the season after scoring twice in 32 Ligue 1 games.

The 18-year-old Frenchman will now join Erik ten Hag and his new team-mates later this week when he joins the Red Devils' pre-season training camp and is likely to be part of the team that heads to the United States.
