Leeds have signed striker Patrick Bamford from Sky Bet Championship rivals Middlesbrough for an undisclosed fee.
The 24-year-old has agreed a four-year deal and moves to Elland Road after the two clubs agreed a reported fee of £7million.
He becomes the White’s fifth summer signing and could make his Leeds debut in Sunday’s Championship opener against Stoke.
Bamford began his career at Nottingham Forest and made two substitute appearances before being signed by Chelsea aged 18 for £1.5million in January 2012. He failed to make a first-team appearance at Chelsea and had loan spells at MK Dons, Derby, Boro, Crystal Palace, Norwich and Burnley.
Middlesbrough paid £6million to seal a permanent move for him in January 2017 and he scored 13 goals in all competitions last season, including a hat-trick against Leeds at the Riverside in March.
Leeds, who appointed former Argentina and Chile boss Marcelo Bielsa in June, signed Jack Harrison on loan from Manchester City on Monday having added defender Barry Douglas from Wolves for an undisclosed fee over the weekend.
Chelsea pair Lewis Baker and goalkeeper Jamal Blackman both arrived on season-long loan deals earlier this month.
