The assistant boss hailed the 17-year-old following his instant impact, after the midfielder came off the bench to make his professional bow and scored the third in a 3-0 victory
Manchester City assistant manager David Platt praised Marcos Lopes following the victory against Watford in the FA Cup, with the debutant netting the third in a comfortable 3-0 win.
The 17-year old pounced on Jonathan Bond’s parry of Mario Balotelli's late effort to tuck home his first for the club just minutes after coming on for his professional bow.
"He's got a big smile on his face at the moment, I can tell you that," Platt told reporters after the game.

"He came away with us on pre-season and did very, very well, he's a very technical footballer, you can see that he wants to go and hurt the opposition.
"He's got great qualities - for the Under-21s he's been scoring goals like that this season.”
It was a routine win for the Premier League champions, with Carlos Tevez and Gareth Barry giving City a two-goal lead at half-time, before Lopes' injury-time strike put the game beyond doubt for the Championship side.
"In the end it was straight-forward, we’re pleased with the result," Platt continued.
"That second goal just before half-time really takes the stuffing out of them and that second half we controlled the way the game was going to be played.
"Goals change games. We went 1-0 up and if we had conceded straight away when they had the one-on-one chance, you never know how it might have gone."
