Cambridge made it two wins from two in Sky Bet League Two as a crushing 5-0 victory over Morecambe moved them to the top of the fledgling table.
Mark Bonner's side produced a superb performance and some clinical finishing at the Mazuma Stadium.
Morecambe actually started the brighter but the game changed on the half hour when veteran midfielder Wes Hoolahan fired the visitors ahead with a superb finish from the edge of the area.
Cambridge doubled their lead four minutes later when former Shrimps striker Paul Mullin curled a superb effort against the crossbar only for the ball to hit Morecambe goalkeeper Jake Turner and rebound into the net for an own goal.
The U's then added a third in the 37th minute with another long-range strike when Adam May was given too much time to drill a low shot past Turner.
The goals continued after the break with Mullin making it 4-0 after 55 minutes with a close-range tap-in after Joe Ironside's header had come back off the crossbar and the same player made it five with a smart finish after being played in by Luke Hannant 10 minutes later.
