Manchester United defender Willy Kambwala has joined Villarreal in a deal worth up to £9.9million.
The Spanish club will pay an initial £4.7m plus up to £5.2m in add-ons for Kambwala who has signed a five-year deal.
United have a buy-back option for the next three years and a sizeable share of any sell-on fee.
The 19-year-old had 11 months left on his contract at Old Trafford and refused terms to sign a new one.
United's decision reflects the club's policy of cashing in on academy graduates who are not going to be first-team regulars or are coming out of contract and could leave for nothing.
