Lyon have agreed a deal to sign Memphis Depay from Manchester United for a fee which could rise to Â£21.7m, according to Sky sources.
Sky sources understand United will have a buy-back option as well as sell-on clauses inserted into the deal that takes the Netherlands international to the Ligue 1 club.
The potential add-ons include Lyon securing qualification for the Champions League and the winger signing a new contract with them.
Depay arrived in Lyon on Wednesday night and will undergo a medical on Thursday ahead of a move to the Parc Olympique Lyonnais.
The 22-year-old joined United from PSV Eindhoven for Â£25m in June 2015 under the management of his compatriot Louis van Gaal, but fell out of favour following the arrival of Jose Mourinho at Old Trafford last summer.
He has featured just eight times for United under Mourinho, with his last appearance to date coming against Feyenoord in the Europa League on November 24.
Depay, who has also attracted interest from Everton, is set to become the second big-name departure from United this month following the sale of Morgan Schneiderlin to the Toffees.
He has played 53 times in total for United, scoring seven goals.
