Wayne Rooney scored his 200th Manchester United goal as David Moyes' side beat Bayer Leverkusen 4-2 at Old Trafford tonight.
The game started slowly as both teams settled into the match with United coming the closest in the opening 20 minutes after Chris Smalling got on the end of a free-kick from Robin van Persie but the ball dipped over the bar.
However, on the 21st minute the Red Devils struck - a fine piece of build up play led to Wayne Rooney getting on the end of a pin-point cross from Patrice Evra.
There was some debate that United's winger Antonio Valencia obstructed the Leverkusen keeper from an offside position, however the goal stood and Rooney celebrated his 199th goal for the Red Devils.
With Fellaini and Carrick in the central of midfield, United took control of the game, with Leverkusen offering a slight threat on the counter attack, however they lacked quality.
United went in at half time a goal up.
Five minutes into the second-half Wayne Rooney latched onto a defensive lapse from the Leverkusen defence and took on the goalkeeper.
With Robin van Persie in the middle, Rooney looked in two minds as he slid the ball across goal for it to get away from United's Dutchman.
And United were made to pay - just minutes later the German outfit went up the other end and scored after a fine strike from Simon Rolfes.
However just five minutes later Moyes' side re-took the lead. Antonio Valencia powered down the wing and put in a cross for Van Persie. Acrobatically the 30-year-old found the net, however the Leverkusen keeper Leno would have felt he could have done better.
On 69 minutes David de Gea made a decent save only to punt the ball forward which led to another defensive error from the Leverkusen defence which once again allowed Rooney in.
And this time Rooney made no mistake as he finished well in the bottom left hand side of the goal and gave the Red Devils a 3-1 lead.
With 12 minutes remaining, United scored the goal of the night - a quite fantastic counter attack - starting with a challenge on the edge of his own box by Van Persie, he found Ashley Young who combined with Rooney to set-up Antonio Valenica, who struck the ball hard and low past the despairing Leverkusen keeper.
With three minutes remaining the German outfit doubled their tally as De Gea struggled to deal with a corner and Omer Torpak struck after the ball rebounded back off the cross bar.
Moments later and United were back on the attack, as the ever dangerous Antonio Valencia put in a superb low cross for Van Persie. However to the shock of Old Trafford, the Dutchman sliced the ball wide as he missed in-front of an open goal.
But the job was already done for United and Moyes will be pleased with an opening Champions League victory.
