The effort marked Fernandes' seventh goal of the season for United and his third in two games.
“This is one thing the coach always says. He always talks to me about this, about putting another wall," Fernandes told BT Sport.
“I can't listen to this because it was so far but Nema and H did an amazing job.
“So with H and Nema in front I think I can try my chance in the side of the keeper.
"Paul knows the keeper or he thinks the keeper can suffer in this side.
“I trusted him and I scored.
“Sometimes you need to do your own thing but sometimes if you listen to your team-mates can help you and help the team and Paul in that moment, he helps me."
