United ran out 2-1 winners at Anfield on Sunday courtesy of two goals from midfielder Juan Mata, the second a sumptuous bicycle kick worthy of winning any match.
Lennon, though, thinks that the whole side deserve credit for the success, which gives Louis van Gaal’s side the edge in the race for the Champions League spots, with their first half performance particularly impressive.
"United were really impressive in the first-half,” Lennon told BBC Sport.
“I thought they controlled the game like the United of old. The sending off in the second-half disrupted their rhythm a bit, but I think they can be immensely proud of the way they played.”
That sending off of Liverpool captain Steven Gerrard will arguably be the moment from the game that dominates the headlines, which will be disappointing considering the quality of the contest overall.
Losing their captain to a red card within seconds of the re-start had the potential to derail the side as well, but rather than dwelling on the red, it seemed to inspire Brendan Rodgers’ side and a goal from Daniel Sturridge offered them hope of snatching an unlikely point.
Lennon was one on many to praise Liverpool’s spirit, but is concerned that the defeat could prove damaging after their recent good run of results.
"Liverpool showed great spirit after going down to 10 men, [but] this will be a tough defeat to take after such a good run,” he added.
