4. Louis Saha
The French international became the club's first ever January signing back in 2004 for a little over £12 million to add a little more depth up front. Solskjaer was struggling with injuries and David Bellion wasn't the best striker to call upon, whilst Ruud van Nistelrooy led the line ahead of an inconsistent Diego Forlan. Having scored 11 goals in 22 games so far for high-flying Fulham it was seen as a good move for a struggling United side, as the striker went on to score 7 in 15 matches for his new club over the rest of the season. Unfortunately Saha is the type of player often given the label of "injury-prone" and his United career never really took off, but 42 goals during his four-and-a-half years at Old Trafford isn't that bad, considering the fact that he was often utilised as a left-winger by the United management. Despite not really having the legs to complete a whole season without injury, his solid performances did earn him a call-up to the France national team. He was a reasonable purchase for the club, but it's a shame as it could have been much better. Source:
