The Italian coach was proud of his side's second half display, but they were too weak in the first half to stop Jose Mourinho's men
Claudio Ranieri said his Fulham side were "lambs" gobbled up by the "wolves" of Manchester United in his side's 4-1 Premier League thrashing at Old Trafford.
Marcus Rashford scored and provided two assists as United ran riot against the league's bottom side, although Aboubakar Kamara replied from the penalty spot.
United were 3-0 up before the break and Ranieri, whose side have one point from three games after beating Southampton in his first game in charge, accepted Fulham were completely outclassed.
