#8 Gerard Pique
A product of La Masia, Gerard Pique served a spell in the youth academy at Manchester United before breaking into the first team in 2005. But, homesickness became the crucial reason behind his departure from England.
At Barcelona, Gerard Pique has stamped his authority as one of the best defenders of the generation. The number of trophies he has won may well be enough for United to get upset about letting him return to Spain.
Frankly speaking, Gerard Pique stood little chance of making the starting XI considering the sturdy defensive partnership of Rio Ferdinand and Nemanja Vidic, who were probably the best defensive duo of the decade. Would you blame Sir Alex for not breaking the partnership in order to draft in a young, inexperienced defender just to grant him playing time?
Despite having Vidic and Ferdinand, Ferguson would, no doubt, have relished holding on to Pique back then.
