Manchester United have had a torrid time this season, falling down the league and struggling to qualify for the Champions League.
David Moyes must first seal a top four place and then attack the transfer market with ferocity.
The Red Devils need additions everywhere but between the sticks and could well be the biggest spenders of the window.
Some reports think they could spend over £100m.
Expect at least one big midfielder to come in but Paul Pogba returning to the club looks unlikely. His team mate Arturo Vidal is looking like a much more viable prospect.
With Nemanja Vidic set to leave, a centre-back of high quality will need to come in and Mats Hummels could fit the bill.
There is a good chance a striker will be coming in as well as Robin van Persie's fitness continues to cause concern. Diego Costa looks like a viable target.
Meanwhile the list of exiting players could role in to the double figures.
Ins: Diego Costa, Mats Hummels, Arturo Vidal
Outs: Nemanja Vidic, Patrice Evra, Nani, Anderson, Alex Buttner, Javier Hernandez, Ryan Giggs
