Manchester United have had a bid, believed to be in the region of £37m, accepted by Chelsea for Spanish midfielder Juan Mata.
The 25-year-old will have a medical on Thursday before completing a move to the Premier League champions.
Mata is expected to sign a four-and-a-half year deal at Old Trafford.
The Spain international, who has won 32 caps, said goodbye to team-mates and staff at Chelsea's Cobham training ground on Wednesday.
