Manchester United manager Jose Mourinho felt the referee and bad luck played a part in his team's defeat to Watford, but also accepted their performance could have been better.
Goals from Etienne Capoue and Marcus Rashford had the match level at 1-1 going into the final seven minutes, when a strike from substitute Juan Zuniga and a penalty from captain Troy Deeney earned the home side a 3-1 victory at Vicarage Road.
United now sit six points behind early Premier League leaders Manchester City and Mourinho has lost three consecutive competitive games in a single season for the first time since he was in charge of Porto in 2001-02.
The frustrated Portuguese felt Anthony Martial had been fouled in the build-up to Watford's first goal from Capoue and suggested his side were on top when Watford struck twice in the latter stages.
He told BT Sport: "In the first half for about 25 to 30 minutes we didn't play well and that is something that we can control. We can improve, we can work on it.
"Then the referee and the linesman's mistake is not under my control. I can't do anything to improve it.
"In the second half we were much better. We get the draw [equaliser] and after that we were the team. Gomes makes a phenomenal save and the lucky moments again are not something we can control.
"We cannot control the referee, we cannot control the lucky moments. The only thing we can control is our individual and collective mistakes."
Mourinho went on to describe the decision not to award a foul on Martial following Miguel Britos' challenge as "ridiculous" and reiterated his belief that factors outside of his control played a key part in the loss.
He said to BBC Sport: "The first factor depends on ourselves, it relates to our individual mistakes and collective mistakes as individual players and as a team. We have to improve something, it is in our hands.
"The second factor is the referee and I can't control their mistakes. The story of the game is the result and not the ridiculous situation of the first goal.
"The third factor is luck, we didn't have it. We were the best team when we lost."
