Manchester United have agreed a £50m deal to sign Chelsea midfielder Andrey Santos.
The agreement is broken up into a guaranteed £48m payment plus £2m in add-ons. Chelsea will also retain a 10 per cent sell-on clause.
Santos is now preparing to undergo a medical with Man Utd.
The Brazil international joined Chelsea from Vasco da Gama and has since played on loan at Nottingham Forest and at Chelsea's sister club Strasbourg.
Santos featured in 43 matches for Chelsea in all competitions last season, scoring three goals and contributing four assists.
Manchester United are also expected to complete a move for Brazil midfielder Ederson, who looks set to move to Old Trafford from Serie A side Atalanta.
Strengthening the midfield has been a priority for United this summer after the departure of Casemiro following the expiry of his contract and the long-term injury sustained by Manuel Ugarte while playing for Uruguay at the World Cup.
