Manchester United have used the transfer market to bring in some wonderful players in their time, but not all of them can be winners.
The transfer market is a tricky thing. Sometimes a signing looks good on paper but is not able to do the business. Sometimes your high-profile signing gets injured. Sometimes they do not like the Manchester weather.
Some of the transfers on this list were actually sensible gambles, which did not work out. Some appeared doomed from the start. Some burned brightly and then faded away, some never caught fire to start with.
All of these signings come from the last 20 years, as it is very difficult to assess the quality or value of older signings without having seen them play.
There are a plethora of options for honourable mentions. Sir Alex Ferguson was fond of a gamble, and they do not always pay off. Michael Owen and Liam Miller escape the top 10 by virtue of being free (and Owen by virtue of *that* goal against City). Kleberson could have a good claim to a spot.
There would even be those who would argue Dimitar Berbatov belongs on the list. They, however, clearly do not appreciate the finer things in life. The hat-trick against Liverpool was almost worth the price of his transfer alone.
Without further ado, here are 10 players whose transfers to United have just not worked out.
