Burnley have had a bid for James Trafford accepted by Manchester City.
The Clarets will pay an initial £15m rising to £19m for the goalkeeper.
Trafford is currently with England at the U21 Euros and still needs to agree personal terms with Burnley.
City have included a buy-back option in the deal.
Last season, former City keeper Arijanet Muric was Burnley's No1 in their promotion winning campaign.
