The 20-year-old's loan spell at MK Dons was recently terminated due to a lack of game-time.
While Rangers currently sit three points clear of both Hibernian and Falkirk at the top of the Scottish Championship, Mark Warburton will be aware of the fact that they have already watched their lead evaporate once this season, and will be desperate to ensure it does not happen again.
One of the options Warburton may consider in a bid to strengthen the Gers' chances of returning to the Premiership is to add further depth up front. Martyn Waghorn has been sensational this term with 18 league goals in 19 games, which is three times the number of strikes managed by Kenny Miller, who is the second highest scoring forward at the club.
With a long way to go in the season, the Rangers boss may be wary of relying solely on Waghorn, and may be looking to strengthen during the January transfer window.
Luckily for Warburton, a very good option appears to have just become available.
Southampton striker Sam Gallagher had moved to Championship side MK Dons in the summer on a season-long loan, but the Daily Echo reports that the 20-year-old has been recalled due to a lack of game-time.
While the former Plymouth trainee's time with the Dons had not been particularly impressive - with no goals coming in his 13 appearances for Karl Robinson's side - his form could be put down to him not being able to enjoy a prolonged run in the team.
He started just six games for the club. And with the Dons having only been promoted last season, it is fair to say that they go into most of their games as underdogs, and thus, are likely to create fewer opportunities for their strikers.
However, Rangers go into almost every game as heavy favourites, and tend to enjoy most of the play, meaning that Gallagher will have more chances to show what he can do, should he complete a move.
The youngster has played at the highest level in England, and has arguably been unlucky not to have been given more opportunities at St Mary's.
And at 6 ft 4 in, Gallagher is considerably taller than any of Warburton's other strikers, meaning that he would bring a different dimension to the squad that would allow the side to adopt a more direct approach if required.
At this stage of his career, joining a side of Ranger's stature is a move that could greatly benefit both player and club. Gallagher simply needs experience of scoring goals, and the Gers would be getting an attacking option with Premier League experience to help them return to the top flight.
