Leeds United have agreed a fee of £7m with Middlesbrough for striker Patrick Bamford, Sky Sports News understands.
The 24-year-old joined Boro from Chelsea on a permanent deal in January 2017 after having previously enjoyed a successful loan spell at the club during the 2014-15 season.
Sky Sports News understands the fee could be worth £10m with a number of add-ons being included in the potential deal.
Bamford scored 13 goals in 44 appearances for Middlesbrough last term as the club reached the Sky Bet Championship play-offs.
He did not make an appearance for Chelsea during his time with the club and had loan spells at MK Dons, Derby, Crystal Palace, Norwich and Burnley as well as Boro.
