Sheffield United took all three points in their Friday night clash with Leeds United at Elland Road, and with it, moved top of the Sky Bet Championship.
The sides were tied 1-1 heading into the final 10 minutes and then stepped up 20-year-old David Brooks for Chris Wilder's side - the starlet netted and sent the Blades faithful wild at the home of their Yorkshire rivals.
The visitors got off to a flying start when Billy Sharp netted in the second minute, thanks to a pinpoint Mark Duffy cross.
Sheffield United seemed in control, and in the ascendancy, but Leeds' Kalvin Phillips had other ideas.
A Samu Saiz cross was headed clear, but it fell to Phillips who struck a sweet first-time volley beyond Jamal Blackman.
1-1 was how it stayed until Wilder introduced Brooks. The young flyer skipped beyond the Whites' defence, and coolly slotted beyond the on-rushing Andy Lonergan.
