A chat with Cavani moments before striking the ball also played a big part.
“Edi before the free-kick told me: 'try a hard one on the side of the keeper'. I tried it and it went in well," Fernandes said.
Despite Fermandes working on his technique of late, he explained it wasn't a forgone conclusion he'd take the set-piece.
“No, no! I think normally a little bit more long distance is for Rash (Marcus Rashford). I think he feels more comfortable [from there], for me it is the same, to go the [closer] distance. I think closer to the box is better for me, for the kind of shot I have," said the Portuguese international.
“Of course, if Juan (Mata) and Alex (Telles) are on the pitch it's a chance for them, more on the right side. I think we have good free-kick specialists. I think we have some players who can take [good free-kicks]. It will depend on the moment. In that moment, I felt I was confident to take the free-kick. It was me and luckily it was a goal.
“I think with this result, with a goal in the last minutes, it would be really good. I think the fans would love it," he added.
