Watford 2-2 Southampton

Abdoulaye Doucoure bundled home a controversial 90th-minute equaliser as Watford fought back from 2-0 down to draw with Southampton.

Doucoure used his right hand to divert Troy Deeney's header past Alex McCarthy from close range to snatch a point for the Hornets.

Two goals from James Ward-Prowse had given the Saints a 2-0 lead at half-time as they looked to be on course to end a run of nine Premier League games without a win.

But Watford came out stronger in the second half, thanks largely to the introduction of Deeney.

They pulled a goal back two minutes before the hour mark as Andre Gray headed home after McCarthy turned Daryl Janmaat's shot onto the crossbar.

Doucoure's late intervention meant the game finished all-square, but Watford have won just once in their past 10 Premier League games.

The home side edged an entertaining first quarter of an hour, but fell behind on 20 minutes as Shane Long's pull-back was deflected into the path of Ward-Prowse, who guided the ball into the bottom corner from 12 yards.

That turned the match in favour of the visitors, and they deservedly doubled their lead a minute before half-time. After Long's determined run down the left, he fed Dusan Tadic on the edge of the area and the Serb helped it on to Ward-Prowse, who netted past an exposed Heurelho Gomes.

The goals took Ward-Prowse's tally to three in his past two games, having failed to score this season before the FA Cup third-round win over Fulham last week.

Video assistant referees (VAR) made their debut in competitive English football this week - during Brighton's FA Cup win over Crystal Palace.

But - after three games in which referees have not had to draw an imaginary TV screen in the air with their fingers, then consult replays of controversial incidents - the system is not being trialled in the Premier League.

How Southampton must wish it was.

Television replays, available within seconds, showed Doucoure used his hand to provide the decisive touch - BBC Final Score pundit Kevin Kilbane describing it as a "clear handball".

"He's got his hand up by his head - it's as clear a handball as you're ever likely to see," he said. "It's a disgrace, an absolute disgrace. Southampton desperately needed this win, and they have been robbed. It's really poor."

It could be argued Watford deserved their point based on their second-half performance, as Deeney showed what they have missed during his four-match suspension.

Prior to the break, the home side could not contain Long, Tadic and Ward-Prowse, but Deeney's introduction changed the game.

Southampton's first-half showing did not fit with a team that began the day outside of the relegation zone only on goal difference.

Watford deserve credit for their fightback but the Saints should have had more about them to avoid such a shift in momentum as they looked to avoid remaining winless in 10 consecutive league games for the first time since January 2005.

Some of that responsibility lies with manager Mauricio Pellegrino, who failed to react quickly enough to Watford adopting a more attacking formation when Deeney was introduced.

The draw lifts Saints up to 16th - ahead of Bournemouth on goal difference before the Cherries face Arsenal on Sunday - but questions remain about the future of Pellegrino.

Do the club's hierarchy want to put the £75m they received for the sale of defender Virgil van Dijk to Liverpool in his hands? Arsenal winger Theo Walcott and Atletico Madrid playmaker Nicolas Gaitan are said to be targets.

Southampton manager Mauricio Pellegrino: "I never see this type of mistake in the Premier League before. To live this injustice is really hard. I think we have to try [VAR] and analyse if it's possible to help the sport to make better decisions, even for the referee.

"Football is like this sometimes, small details change everything. We are very sad but we have to accept the rules. It's part of football. Even in the second half they were playing more direct, I don't remember many clear chances, just second balls. They are stronger than us in this physical battle.

"The last four games the team is growing. Playing in this way it's easy for everybody because I'm sure we'll win games."

Watford manager Marco Silva to Sky Sports: "I have a different opinion. I talk about the match, two different halves.

"I don't need to talk about the goal. Something can happen and this season we've had decisions go against us. I understand Southampton are unhappy like I was not one time, more than one time when the mistake is against us. It can happen."

Watford travel to Leicester City on Saturday (15:00 GMT), while Southampton have an extra day to prepare for the visit of Tottenham (16:00 GMT).

The pair will meet again later this month in the fourth round of the FA Cup, this time at St Mary's on 27 January (15:00 GMT).
