Claudio Ranieri has suggested that Leicester City will find it hard to preserve their high-flying form against Manchester United's "fantastic" defence this weekend.
Saturday throws up a top-of-the-table clash at the King Power as Premier League leaders Leicester host the Red Devils, who sit one point back in second.
No team has scored more than the Foxes this term, but Ranieri warns that it could be tough to improve on their 28-goal season against the Red Devils, who have conceded just nine times - fewer than anybody else.
"Manchester United's defensive line is fantastic," the Italian told reporters. "They defend like a unit and it's difficult to break their lines."
City have lost just once this season.
