However, the 21-year-old's presence at Old Trafford is more a simple numbers game then the Red Devils plucking a new superstar out of left field.
Kellett, who had to be convinced that his move to United was not a hoax, has struggled to make an impact at the Trotters, and while this isn't usually a precursor to a switch to the Premier League, his position on the periphery at Bolton is the reason for his transfer.
United didn't bring in the big names some would have expected them to land in January, but they were very successful in sending a number of fringe players out on loan or, in the case of those surplus to requirements, on permanent transfers.
Youngsters Michael Keane, Ben Pearson, Sam Johnstone, Will Keane, Marnick Vermijl and Ben Amos have all left the club, and while this is good business for United, it has left their development squad looking a little thin.
As a result, when it was decided that Swiss teenager Saidy Janko could benefit from a spell fighting for a first team spot at Bolton, the Red Devils needed to replenish some of their numerical loses, and so Kellett was sent in the opposite direction.
