(CNN)It was a mixed return to his boyhood club for Memphis Depay.
Although the 21-year-old scored against PSV Eindhoven with an extraordinary goal in the 40th minute -- and celebrated as promised -- Manchester United went home without earning any points in the first round of their Champions League campaign.
The final score was 2-1 to PSV, who benefited from goals by Luciano Narsingh and Hector Moreno, despite United controlling 67% of possession.
Moreno was also involved in a play in the 14th minute that left United's promising young left back Luke Shaw writhing on the ground in pain.
The Mexican defender, who was not called for a foul on the hard tackle, caught Shaw with his trailing leg in an unfortunate high-speed collision which will likely take the 20-year-old out of action for months with a suspected broken leg.
Shaw was showing bright signs as a regular on the United squad after his £30 million purchase from Southampton in 2014. It took 10 minutes for medical staff to remove Shaw safely off the pitch in a stretcher while he breathed out of an oxygen mask.
"It's a very sad time and we wish him a quick recovery," said United defender Chris Smalling after the match, adding that the diagnosis was still uncertain.
Shaw himself tweeted out his gratitude to the fans for all their well wishes, saying he was "gutted" and "will come back stronger."
Memphis Depay, who helped PSV win the Eredivisie league last year by chipping in 22 goals, speculated before the match that his boyhood club's fans would allow him the indulgence of celebrating should he knock one in for his new team.
And, with a clinical build up that eluded two defenders before slipping the ball in between PSV goalkeeper Joreon Zoet's legs, Depay raised his arms and celebrated in style. The away section went wild, while the home fans politely acknowledged that their former talisman had moved on to greener pastures (while netting PSV approximately $38 million).
"If I score I will celebrate," he said in an interview before the match. "I have a lot of respect (for PSV) but everyone can understand, when I score I celebrate."
"It's a great stadium, great atmosphere and a lot of memories. This is my second home and Manchester is now my new home," he added.
