Chelsea boss Antonio Conte says Manchester United parade one of the best squads in England.
Holders United will travel to Stamford Bridge on Monday to face Chelsea in one of the quarter-finals of the Emirates FA Cup.
United will however be without Zlatan Ibrahimovic who will commence his three-match ban for violent conduct against Bournemouth's Tyrone Mings.
At Friday's press conference ahead of the game, Conte said: "I am preparing to face a great team on Monday. Along with Man City, Man United have the best squad."
Conte, whose Chelsea team defeat United 4-0 in their Premier League clash earlier in the season and are currently 10 points ahead in the race for the Premier League title, added: "The most important thing in the build-up to a game like Monday's is to prepare and focus on what will happen on the pitch.
"There are no injury problems with two training sessions to go to the Man United match.
"I am yet to decide the team I will select for the match."
