The Blues welcome United in a much anticipated FA Cup quarter-final clash at Stamford Bridge on Monday and Conte is expecting a difficult game.
Jose Mourinho’s men have not lost in the league since they were thrashed 4-0 by Chelsea on October 23.
But Conte says the Red Devils and Pep Guardiola’s men are superior to his squad.
“I think Manchester United, with City, have the best squad in the league,” Conte told reporters on Friday.
“They have a lot, a number of great players with great talent and great experience to win.
“For sure, it can be a really tough game, for us and for them. I think that now, for us, it is better. We have a good identity, a good team. So we are showing good football.
“But, for sure, it will be a really tough game against United. We are facing a good team, very strong”, he said.
