The January transfer window is almost upon us.
It is always interesting to see how heavily clubs invest in the winter transfer window because teams doing well seldom try to fix what's not broken while struggling sides spend desperately in a bid to save their season.
Manchester United fans will be keenly watching how much say caretaker manager Ole Gunnar Solskjaer is given in the recruitment process considering the fact that he is only in temporary charge of the Red Devils after Jose Mourinho was sacked last week.
Solskjaer seems to have been led to believe that he will have some input into any signings made in January and that made us wonder how successful previous mid-season signings have been for United.
In total, 17 players have signed a contract with United during the January transfer window since the turn of the century. And we want you to name as many as you can.
If the quiz doesn't display for you properly, click here.
To make matters a little easier, we've included the year that each player signed and where they're from (in cases when there has been a dispute over which national team the player elected to represent, we've included two countries.)
We will admit that there is an obscure player or two in the bunch so 100 per cent is almost impossible.
Best of luck and let us know how you get on.
