Nani was delighted for Javier Hernandez after the youngster struck in Manchester United's defeat of Stoke City.
It was Chicharito's his ninth goal of the season, and second in four days, to emphasise just what a valuable contribution he has made so far.
"Javier has had a great start to his Manchester United career," said Nani.
"He always scores at the right moment, when we need it. He has been a key player this season."
