Tottenham Hotspur manager Jose Mourinho insists he has no issues with goal-line technology after his side played out a goalless Premier League draw at Watford on Saturday. In a largely uneventful match, Troy Deeney had a second-half penalty saved by Spurs keeper Paulo Gazzaniga before Erik Lamela's stoppage-time effort was cleared off the line by Watford substitute Ignacio Pussetto, who was making his debut for the club. Goal-line technology showed 10.04mm of the ball had not crossed the line. "I am happy with how we played, our commitment. I think the result is unfair, I think it would have been more unfair if we lost," Mourinho told the BBC. "We are not good at adapting to this style of football. We were quite difficult to play." Despite goal-line technology denying his team a potentially match-winning goal, Mourinho said he had no problem with the decision or the technology in general. "I know it was only a couple of millimetres but goal-line technology does not make mistakes like VAR. We have to accept it was not a goal," he said. "I love goal-line technology, I respect that." The draw continues the fine start made by Watford manager Nigel Pearson, who has now guided the club to 14 points in the past six games, and the Englishman said he was pleased with his team's efforts. "It’s football," Pearson said when asked about the penalty miss. "I said to the players I am looking for a performance and we had a good performance today. If we go out with every intention to win the game then we will play well. I am pleased with how we played football today." Tottenham's arch-rivals Arsenal were also held to a draw after Sheffield United struck a late equaliser at the Emirates Stadium. Gabriel Martinelli opened the scoring for Arsenal in the 45th-minute before John Fleck struck back for the visitors with seven minutes remaining as the promoted club remained four points clear of Saturday's opponents. The result means new Arsenal manager Mikel Arteta has overseen just one win in his first five games. Norwich City gave their hopes of survival a major boost by defeating relegation rivals Bournemouth 1-0 at Carrow Road. Striker Teemu Pukki scored the only goal of the game when he converted a penalty in the 33rd-minute, two minutes after Bournemouth Steve Cook was sent off for deliberately handling Ondrej Duda's goal-bound effort. Norwich were also reduced to 10 men when Ben Godfrey was sent off in the 76th-minute for a late challenge on Callum Wilson. "It is huge. We have played well lately but haven't got the three points," Pukki told the BBC. "It was important for the team and for confidence. There is a big road ahead but we are ready to fight." In the highest-scoring game of the day, Wolves fought back from 2-0 down at Southampton to win 3-2. Jan Bednarek and Shane Long had given Southampton a comfortable half-time lead before Pedro Neto and a double from Raul Jimenez turned the game in Wolves' favour. Elsewhere, there were 1-1 draws between Brighton & Hove Albion and Aston Villa at the Amex Stadium, and at the London Stadium where West Ham entertained Everton.
