Louis van Gaal says he is proud to manage Manchester United after they scored a stoppage time winner to move, temporarily, top of the Premier League.
Bastian Schweinsteiger saw his shot slid into the net by Troy Deeney in the 92nd minute for United's first goal in stoppage time since Sir Alex Ferguson retired in 2013.
The three points leaves United ahead of Manchester City and Arsenal after playing before their title rivals. City face Liverpool later on Saturday while Arsenal play West Bromwich Albion.
Van Gaal says United are fighting for the title and was impressed by the spirit of his side against Watford in the Saturday lunchtime kick-off.
Van Gaal happy with spirit of United
"I was amazed by the spirit in our team," Van Gaal said after the win, speaking to BT Sport. Memphis Depay opened the scoring in the 11th minute but Deeney's late penalty had many assuming the Reds would drop points.
They responded well, though. Jesse Lingard had a shot saved from a corner and Schweinsteiger pounced, shooting from a tight angle and forcing Deeney to slide it into his own net.
Van Gaal says United are challenging for title
"I am very proud to be manager of this team," Van Gaal said. "We are fighting for the first position in the Premier League."
Memphis was filling in for Anthony Martial and captain Wayne Rooney who were both unavailable for Saturday's game and as well as the goal, he looked very good.
Van Gaal said, "In the first half he was superb. I think he role is the best role for him. I knew he could do this."
United are top of the table for now, and play PSV Eindhoven on Wednesday night as they look to secure qualification to the knckout stages of the UEFA Champions League.
