Middlesbrough midfielder Barry Robson was furious with himself after their FA Cup draw against Sunderland.
The Scotland international, whose stunning 16th-minute volley had fired the npower Championship visitors into the lead at the Stadium of Light, played a part in Campbell's 59th-minute equaliser when his loose pass set James McClean away on a pacy counter-attack.
Robson's error did not prevent him from picking up the man of the match award at the end of a pulsating fourth-round encounter, but manager Tony Mowbray revealed that proved little consolation.
"He is a very emotional boy, Barry, and yet he epitomises the spirit required as we as a club move on.
"Particularly in the Championship, you have to fight your corner every minute of every game, and Barry Robson leads from the front in that aspect.
"He also has a left foot like we have seen. If you were there against Hull a month or so ago, he rifled one in the top corner from 35 yards with his left foot.
"Today, he scored a great first-time volley. He has the quality, as well as a heart the size of a lion, to help drive us on this season."Mowbray said: "He came in and he threw his champagne in the bin.
