It has since been claimed that Boro are investigating Monk for the signings which took place during his tenure at the Riverside in 2017, in particular Cyrus Christie, Ashley Fletcher, Ryan Shotton and Marvin Johnson. We take a look at the players who joined Boro under Monk and what has happened to them since:
5. Ryan Shotton
After barely featuring under Monk, Shotton became a consistent starter under Pulis. The defender made 34 league appearances for Boro last season. Photo: Tony Marshall
6. Lewis Baker
Baker signed for Boro on a season-long loan in 2017 but made just 12 league appearances for the Tessiders. After returning to his parent club Chelsea, the midfielder was loaned out to Leeds and Reading last term. Photo: George Wood
7. Marvin Johnson
After some promising early flashes, Johnson quickly fell down the pecking order in his first year at the Riverside. He spent last season out on loan at Sheffield United, where he made 11 league appearances, and is now back training with Boro. Photo: Alex Livesey
