Anel Ahmedhodzic was all things to Sheffield United as his new club moved menacingly into the Championship play-off places.
The 23-year-old Bosnia and Herzegovina defender, signed from Malmo during the summer on a four-year deal, was the goal hero with a thumping 33rd-minute header.
And then he was the creator supreme, driving into the heart of the Sunderland penalty box before showing intelligence to cross for Max Lowe to tap home a second.
The goals from Ahmedhodzic and Lowe were their first for the Blades and ended 10-man Sunderland's long unbeaten league run dating back to February.
