Antonio Conte told Sky Sports he blamed himself for Chelsea’s 2-0 defeat to Manchester United in the Sunday’s English Premier League match at Old Trafford.
He said Jose Mourinho’s team showed “greater desire and motivation to win the match.”
An early goal from Marcus Rashford and a deflected strike from Ander Herrera were enough for Mourinho to earn his first victory against Conte’s Chelsea at the third attempt.
The Premier League leaders failed to register a shot on target in a Premier League match for the first time since December 2015, and the result means their lead over Tottenham Hotspur is just four points with six games remaining.
Conte said his players must have great enthusiasm, passion and motivation to play this type of game from now until the end to reach the target of winning the title.
“It’s a fantastic target because if we are able to reach it it’s a miracle. We must find the right motivation. We stay in a great position but Tottenham is in great form and playing with great enthusiasm. We must find the same.”
Manchester United manager Mourinho said Rashford had played “fantastically well” after the striker gave Chelsea’s defence a torrid time.
Mourinho left top scorer Zlatan Ibrahimovic on the bench after Thursday’s 1-1 Europa League draw at Anderlecht, with the Swede having complained of tiredness.
Replacement Rashford made the breakthrough as United threw the title race open, and kept their own top-four hopes alive, with Ander Herrera adding the second goal.
Mourinho told Sky Sports: “Marcus Rashford played fantastically well.
“He had a very good game at Stamford Bridge in the FA Cup, exactly the same chance to score, because he is faster than their defenders.
“Today he scored and it gave the team more confidence, more stability.”
He said United went to Stamford Bridge for the FA Cup quarterfinal tie with same tactics and had the game under control with 11 players.
“Only the decision that made us play with 10 men for the second half and 10 minutes in the first half gave Chelsea a chance to be dominant.
“We knew that playing this way would be very difficult for them.”
United’s performance was one of their best since Mourinho took charge last summer and the Portuguese praised his team’s attitude.
