Gerard Deulofeu's game-changing cameo in Watford's 3-2 FA Cup semi-final win over Wolves was fuelled by anger, according to Hornets boss Javi Gracia.
Deulofeu netted his second of the game in extra time, completing a remarkable comeback at Wembley and booking a final showdown against Manchester City next month.
Goals from Matt Doherty and Raul Jimenez meant Wolves were 2-0 up by the time the former Barcelona winger was introduced from the bench midway through the second half and he reduced the arrears with a sumptuous chip in the 79th minute.
