It is not just Chris Wilder strengthening his ranks this month, United Ladies boss Dan O'Hearne has also made a number of important additions.
United have responded positively to the loss, before Christmas, of captain Rosa Neary due to injury. The popular central defender is not expected to be back playing until pre-season after damaging her ligaments in a 50/50 tackle.
O'Hearne has moved quickly to bring in two experienced central defenders to bolster the current squad's push for a league and cup double.
Nat Froggatt, 29, formerly at Steel City, Junior Blades and United from 2010 to 2013, returns after a spell out of the game and is expected to replace Neary directly as Molly Cawthorn's central defensive partner for the rest of the season.
In addition, Christina Skull, 31, is equally well-known in South Yorkshire women's footballing circles after playing for home town Chesterfield then Sheffield Wednesday before teaming up with Froggatt at United in 2012.
Skull played in the three seasons in the Northern Combination for United which ended in relegation in 2015. She returns after a period in France and after her international clearance was granted, she initially takes up a role in central midfield.
"It's great to be back in the red and white again," said Skull "It's so good to see how the club is progressing and seeing the squad becoming stronger and stronger. Dan (O'Hearne) has stuck by the girls through thick and thin and the hard work is paying off. I hope to be part of further progression and hopefully help in gaining promotion back to the level where the club rightfully belong."
Experienced player Rachel Ruddach added about the signings: "It's a great morale-boost to the squad after losing Rosa. Two massive characters who bring both height and experience to the team."
The duo, pictured, made their comebacks in the County Cup win at Steel City, whilst United have also signed two younger players in Sheffield Hallam University students Pheobe Dunne and Holly Fowler, taking the total number of new signings to four.
