United had failed to beat Chelsea in their last 12 games but they were the undisputed better side on Sunday and they seized the moment to condemn the table toppers to a rare defeat.
After Sunday’s game, Conte told Sky Sports News: “They deserved to win, because they showed more desire than us, more motivation. In this case, the fault is of the coach. It is mine. In this case I wasn’t able to do the right motivation.
“To play this type of game from now and until the end we must have great enthusiasm, great motivation to try to reach the target. This for us is a fantastic target.
“I have concern because we have to work together and find quickly the right ambition to win this title – if someone thinks it’s normal for Chelsea to win the title, we started as underdogs after 10th place last season.”
United are now four points adrift of fourth-placed Manchester City in the table with a game in hand to play, while Chelsea’s advantage on closest challengers Tottenham Hotspur at the top remains at a slender four points.
