"Garnacho scored a banger but didn't celebrate like he should because he thinks he has lost faith from some fans," Fernandes, who scored United's opener, told BBC Sport. "I told him people will always moan but lots of people like you and enjoy what you do.
"I told him to celebrate, it was something special. He is a special player, we have difference-makers. They are the ones who win us games. We want them to score every game but that isn't going to happen."
