The Spaniard played a key role in the 2-0 victory over table-topping Chelsea on Sunday, setting up Marcus Rashford's opener before scoring the second of the game.
At the heart of the home side's display was a virtuoso performance from midfielder Ander Herrera, with the Spanish worldwide setting up the first goal and scoring the second.
Mourinho set his team up in a similar way when United fell to a 1-0 defeat at Stamford Bridge in the FA Cup last month after being reduced to 10 men following Herrera's red card.
Rashford's display suggested he deserves to be given more chances through the centre, where United's top scorer Zlatan Ibrahimovic - rested on Sunday - has started nearly every game this season.More news: US Carrier Strike Group Now Actually Heading to North Korea, Officials Say
"We didn't play a good game and United deserved to win the game", said Conte.
Young was as proud of the display as he was to captain United for the first time, saying "every man was fantastic from start to finish" as his side stylishly ended a frustrating run of home draws. Tottenham now trail them by four points with six games to go and have the superior goal difference.
But he conceded: "I think it was a special performance because it was a special opponent - the leader".

"I wasn't able to transfer the right motivation to play this type of game".
"The satisfaction [of winning the game] is for different reasons", said United manager Jose Mourinho. Over 32 games they've proved themselves the best team in the league, they're still top, and have more than enough to get the points they need to become champions. It's still the favorite to win the Europa League and has an away-goal edge over Anderlecht after the first leg of their quarterfinal.
"I have to go in the direction of the players, but they also have to go in my direction. Getting the points has massive importance so we've just got to keep going in the league and the Europa League as well", he said.
"I am happy with my development and I am happy with my performances, but people remember the end of the season and now we are in the crucial moment", Herrera told United Review.More news: Thousands at Stockholm 'Lovefest' vigil against terror
