Jose Mourinho says champions Leicester City will be easy to analyse but very difficult to beat when his Manchester United team host them at Old Trafford.
Claudio Ranieri's side won their first Premier League title by 10 points in 2015/16, losing just three matches.
And after a stuttering start to their title defence, the Foxes have won two of their last three fixtures and triumphed on their UEFA Champions League debut against Club Brugge.
Man Utd manager Mourinho told manutd.com: "They won the league because they were very good and still are very good.
"They are a very easy team to analyse because their defensive process and attacking organisation are clear, but it is very difficult to cope with it."

Man Utd go into the match after back-to-back Premier League defeats, following victories in their opening three encounters of the campaign, and Leicester manager Ranieri says his side are relishing the occasion.
"We are fearless," Ranieri told lcfc.com. "Why are we scared to go there? More than lose, what can we do there? I enjoy [the atmosphere]. Amazing, fantastic."
