Two last-gasp goals helped Watford come from behind to beat Crystal Palace on Gianfranco Zola's first Championship game in charge.
Owen Garvan put Palace ahead on 13 minutes from the penalty spot, before Martin Taylor levelled the scores with a close-range tap-in nine minutes later.
Garvan struck again just before the half-hour mark to restore his side's advantage.
Watford responded well to the setback and, after dominating for large periods in the second half, they levelled again two minutes from time.
Almen Abdi's powerful effort from 20 yards nestled in the bottom corner of Julian Speroni's goal, despite the Argentinean keeper getting his fingertips to the shot.
Deep into stoppage time, Matej Vydra grabbed a sensational winner with a curling effort from 20 yards.
