United were dealt a huge blow in midweek, as first choice left back Luke Shaw sustained a season-ending injured, suffering a double leg fracture against PSV Eindhoven.
That leaves United somewhat short of options at left back, and whilst Daley Blind or Marcos Rojo could fill in there, manager Louis van Gaal may want a more natural solution in his defence.
Now, The Sun report that manager Louis van Gaal is weighing up a move to sign West Ham fan favourite Aaron Cresswell in January as a replacement for the crocked Shaw.
Cresswell, 25, joined the Hammers from Ipswich Town in the summer of 2014, and immediately adjusted to life in the Premier League with a superb campaign at Upton Park, impressing with his marauding runs up the left flank.
The Liverpool-born defender has continued his form into this season too, and now it seems that his performances have attracted interest.
The Sun report that Van Gaal will see how United cope without Shaw until January, but that if he wants a solution in the New Year, West Ham's Cresswell is the most likely target in a £15m move.
West Ham co-chairman David Sullivan told The Mirror earlier this week that the Hammers may have to sell in January after a big summer of spending - and rumours of a move from United for Cresswell may just concern supporters in East London.
