Abdoulaye Doucoure scored a last-minute equaliser as Watford fought back from 2-0 down to draw with Southampton.
Southampton took the lead on 20 minutes at Vicarage Road when James Ward-Prowse slotted past Heurelho Gomes.
The visitors were on course for a first win in 10 Premier League matches when Shane Long crossed for Dusan Tadic to set up Ward-Prowse for his second.
Andre Gray pulled one back on 58 minutes, pouncing on the rebound after Daryl Janmaat's shot had been tipped on to the crossbar.
The comeback was completed when Doucoure bundled in substitute Troy Deeney's header, albeit with the ball hitting his hand in doing so.
Watford: 20 Jan v Leicester (A)
