The young star has since developed into one of the most exciting talents in the European game and just the type of player that the outgoing Premier League champions crave in their midfield.
The 21-year-old’s United contract expires this summer with no news on an extended deal for the striker, who has only ever made one appearance for the Manchester club in the Premier League.
Keane has been out on loan at Wigan and is currently with QPR, while he has represented England at under-16 through to under-21 level.
If the young starlet does opt to leave United this summer there will surely be plenty of teams ready to snap him up.
Just whether major sides such as Juventus or Arsenal would make their move remains to be seen, as although talented Keane is not as much of a prospect as Pogba was.
For United, a summer of spending on new players is expected, with first-team opportunities for Keane not likely to be forthcoming any time soon.
