Middlesbrough have signed Nottingham Forest forward Britt Assombolonga for a club-record £15m.

The 24-year old scored 30 goals in 47 league starts after joining Forest from Peterborough in 2014.

The Congolese striker has been brought in to help fire Boro back into the Premier League after their dismal total of 27 goals subjected them to relegation last season.

Assombolonga said: "I can't wait to get started and train with the boys. I'm glad it's completed and I can focus on what's ahead now.

"I can't wait to meet the manager and get ready for next season. There's a good feeling around the place. From the minute I walked in it felt right."

Assombalonga becomes Garry Monks' fifth signing, following the permanent transfers of Jonny Howson, Cyrus Christie and Martin Braithwaite as well as a year-long loan deal for Connor Roberts.
