Watford came from two goals down to overcome Wolves 3-2 on Sunday in a FA Cup semifinal at the Wembley Stadium; the result handing them a date with Man City in the final of the competition.
Strikes either side of half-time from Matt Doherty and Raul Jimenez put Nuno Espirito Santo's side on the path to a May 18 meeting with Manchester City but Javi Gracia responded by sending Deulofeu on for Will Hughes and the Spanish winger scored an outrageous chip before Troy Deeney drilled home from the penalty spot in second-half stoppage time.
While Deulofeu's first was special, the one Watford fans will most treasure came when he showed absolute composure to slide home in the first half of extra time and end Wolves' hopes of a return to the FA Cup showpiece after 59 years.
Jonny Castro Otto and Joao Moutinho curled efforts over from 20 yards as Wolves started brightly and they went ahead when an unmarked Doherty nodded Diogo Jota's cross home nine minutes before half-time.
Jimenez struck a fierce shot straight at Heurelho Gomes early in the second half but saved his best for the 62nd minute, controlling Doherty's cross on his chest before acrobatically converting with unstoppable power and celebrating with a Wolves-themed Mexican wrestling mask.
