Halford has made himself a Lane icon this season, and admits he is loving life in S2. We're led to believe that the Blades will sign the 24-year-old for a fee to be around the £1.5m mark.
United are still vying for promotion in the topsy turvy play-offs, but we believe manager Kevin Blackwell will snap up the Black Cat regardless of what league we are in next August.
Halford has netted eight goals in all competitions this season, from defence, midfield and up front, and has featured 48 times this campaign (10 sub apps). Greg of course netted the winner in Sheffield United's two legged tie with Preston in the semi-finals of the Championship play-offs.
