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.
