Patrick Bamford has joined Middlesbrough on a permanent transfer from Chelsea. The striker has moved to Teeside for an undisclosed fee, thought to be £6m, signing a four-and-a-half-year deal.

Bamford, who scored 19 goals on loan at Middlesbrough in 2014-15, was recalled this month by Chelsea from a loan spell at Burnley, for whom he made six appearances.

The 23-year-old did not make a first-team appearance for Chelsea, whom he joined from Nottingham Forest in January 2012.

The England age-group international had three loan spells at MK Dons, one at Derby and at Boro in the Championship, helping them to the play-off final, where they lost to Norwich.

Last term he had Premier League stints with Crystal Palace, Norwich and then began this season at Burnley, before the recall paved the way for the move to the north east.

Bamford is Aitor Karanka’s second signing of the winter transfer window, after Rudy Gestede switched from Aston Villa.
