The Teessiders spent over £50million following their relegation from the Premier League when Garry Monk was appointed at the Riverside.
Boro brought in 11 players during that transfer window in their attempt to return to the top flight, and it’s fair to say the signings have been mixed.
The exits of Assombalonga and Fletcher, who both signed four-year deals when they arrived at Boro, means that Jonny Howson and Marvin Johnson are the only players left at the club who signed when Monk was in charge.
We take a closer look at the other players who joined Boro during that period, including loan deals, and what has happened to them since.
There are 11 players on the list.
