Chelsea boss Maurizio Sarri reckons the players at Jose Mourinho's disposal at Manchester United are the best in the Premier League.
Chelsea's only defeat this season came in the Community Shield to Manchester City, who lead the Blues and Liverpool on goal difference at the top of the Premier League.
Mourinho, meanwhile, is embattled at United, who are eighth after three losses in the opening eight games.
"They are a very strong team. Maybe player by player they are the best team in the Premier League," Sarri said.
"At the moment I think City are better like a team, but player by player they (United) are very, very strong."
That may be interpreted as implied criticism of Mourinho, but Sarri was not about to emulate his predecessor, Antonio Conte, in igniting a public feud with the former Porto, Inter Milan and Real Madrid boss.
"We are talking about a coach who has won everything," said Sarri, who is yet to win a trophy in his management career.
"He has won everywhere. So I think that I have to respect him. But I think, also, that you all have to respect him."
