A number of Blades will soon be returning to the club, having been away on international duty.
David McGoldrick and Enda Stevens have both impressed whilst away with the Republic of Ireland, with the duo starting both qualifying victories over Gibraltar and Georgia, games which the Irish won 1-0.
John Egan was also in Mick McCarthy's squad for those fixtures but was an unused substitute.
John Fleck didn't feature for Scotland in Kazakhstan or San Marino, whilst Conor Washington had a watching brief for Northern Ireland's victories over Estonia and Belarus at Windsor Park.
For England U21s, Everton loanee Kieran Dowell has featured twice, in the draw with Poland, where he played 80 minutes and Tuesday's defeat against Germany, a game where fellow loanee Dean Henderson played 90 minutes.
