Tottenham manager Jose Mourinho felt it was “unfair” his side only came away from Vicarage Road with a draw after they were held by resurgent Watford, who missed a penalty.
Troy Deeney saw his spot-kick saved, but the Hornets extended their unbeaten run in the Premier League to seven matches.
Paulo Gazzaniga dived low to his right to deny the Watford captain following Jan Vertonghen’s handball in the second half.
But Mourinho told BT Sport afterwards: “I think we deserved to win this match. To lose would have been too harsh on the boys.”
Watford goalkeeper Ben Foster saved from Lucas Moura before half-time to thwart Spurs, who have now gone four league games without a win.
“The result is unfair. I think it would have been more unfair if we lost,” added Mourinho.
“We had the control of the game, especially in the first half. We arrived in dangerous positions. We created chances but we did not manage to score.”
Deeney had headed a good chance straight at Gazzaniga just before the break, while Abdoulaye Doucoure shot into the side-netting early in the second half.
Watford substitute Ignacio Pussetto, making his debut for the club, cleared an Erik Lamela effort off the line in stoppage time at the end of the match.
Winger Pussetto, a £7m signing from Udinese, had only been on the pitch for just over a minute when he slid in to hook away with almost the whole ball over the goalline.
The Hornets, who were bottom of the table when manager Nigel Pearson took over in December, are now 17th, while Spurs are seventh.
