Abdoulaye Doucoure scored a late, controversial equaliser to earn Watford a dramatic 2-2 draw against Southampton.
Midfielder James Ward-Prowse scored twice for Mauricio Pellegrino's side in the first half but Andre Gray pulled one back for Watford just before the hour mark, before Doucoure levelled things up in the last minute.
Ward-Prowse's first goal came thanks to determined work from Shane Long down the right who pulled the ball from the right for the midfielder to calmly slot home.
Southampton centre-back Wesley Hoedt almost made it 2-0 in the 26th minute when he decided to try and chip Heurelho Gomes from 40 yards but the goalkeeper just about got back in time to divert the ball away.
Following their FA Cup escapades last week, there were a few changes for both teams. There were three changes for Watford as Ben Watson, Richarlison and Andre Gray came in for Etienne Capoue, Roberto Pereyra and Troy Deeney. Mauricio Pellegrino mixed things up at the back by replacing Jan Bednarek and Maya Yoshida with Cedric Soares and Wesley Hoedt, while Dusan Tadic came in for Sofiane Boufal further up the pitch.
The home team were second best in every department, summed up by Daryl Janmaat losing a 50-50 with Tadic, allowing the Southampton man to cross for Long who would have scored if it wasn't for a last-ditch block from Marvin Zeegelaar.
It was Long's work-rate which brought the second goal as he raced onto a clearance, before playing in Dusan Tadic who held the ball until Ward-Prowse reached the area and the laid it off so he could get his second of the match.
Troy Deeney's half-time introduction made Watford look a more dangerous side, and he set up Janmaat for a shot which Alex McCarthy had to tip onto the bar, only for Gray to head home the rebound from three yards out.

Man of the match: Troy Deeney</b>
After considerable pressure from Watford, Doucoure finally made it pay when he latched onto a chipped pass from Deeney in the 90th minute, but the midfielder missed the ball with his head so palmed it beyond the onrushing Alex McCarthy.
There were protestations aplenty from Southampton and Doucoure looked very sheepish as he ran off to celebrate after a quick look at the assistant referee but the goal stood.
The draw means Southampton, who sit in 16th place, have not won in the last 10 games, while Watford are in 10th.
In a week's time, Watford will travel to face Leicester.
Southampton have a tough task ahead of them on Sunday, January 21 when they host Spurs, live on Sky Sports Premier League.
Man of the match - Troy Deeney
The Watford skipper was inspirational after he came off the bench at half-time. Deeney brought increased physicality and guile in the final third as Watford played with two strikers in the second half. He was involved in both goals even if the second one should not have stood.
