Chris Wilder has already been active in the transfer market this window and yet more could be joining the ranks at The Riverside before the window slams shut on deadline day.
Boro know that a good window could be the difference between a late season promotion push and yet another season in England’s second tier.
In the world of transfers, you can often get bogged down by the volume of players linked with your team and so here, we offer a little respite and some fun.
We have used the game Football Manager to see who they believe are the most likely players to join Boro this month.
To do so, we simulated three January transfer windows and listed every player that joined Middlesbrough in those simulations.
Would you like to see any of these join this month? Follow us on Twitter @Boro_Mail and let us know there.

1. Simulation One - Gonzalo Carneiro
Clearly, Wilder felt that he needed firepower up-front as Carneiro was actually signed in all three simulations. His best form in front of goal came in the first simulation where he notched seven goals as Boro lost in the playoffs to Swansea City.

2. Nabil Bentaleb
The former Spurs midfielder was available on a free and duly snapped up by Boro. Despite his Premier League experience, Bentaleb failed to impress at the Riverside.

Not to be confused with the Shakhtar Donetsk centre-back of the same name, Marlon is a left-back that was also picked up on a free transfer by Boro in two of the simulations. His best form came in this season that ended in playoff heartbreak.

4. Julian Jeanvier
In a deal that involved Paddy McNair moving the opposite way to Brentford, Jeanvier became an important part of the Boro defence as the 29-year-old helped keep six clean-sheets in just 15 appearances.
