The young forward's decisive flash of penalty-area inspiration settled an otherwise largely forgettable match at the Mestalla, but the substitute insisted the outcome - a vital one-nil win for the Reds over main Group C rivals Valencia - mattered more than any personal glory.
"It was a great night. I am so happy about the goal but also it was important to get the win and three points," said Chicharito. "I am glad I was able to play my part in the win. But our defence was very solid tonight. We appreciate that as players up front."
Netting in Europe realised a dream for Chicharito, who previously watched from afar.
"I used to watch the Champions League at home in Mexico," he said. "It is one of the most important tournaments in the world and to score in it, so early in my United career, is a dream come true, and a big boost. It will give me so much confidence."
The fact his 85th-minute winner came from the best team move in the match was not lost on the scorer - "It was some great play by Nani to keep the ball and then he set Kiko away. It was a great ball in from him and I was able to put it away."
From scoring at Wembley against Chelsea to kickstarting the club's European quest, Chicharito continues to take everything in his stride - "I am settling in well in Manchester. I have been learning and working hard because I want to do well here, I am very motivated. I am enjoying it, it's great to be a United player, and I want it to continue for a long time."
