Andreas Pereira has explained how Manchester United's training session on Friday gave him confidence to score his first Premier League goal against Southampton .
"It's my best day," Pereira said. "My first Premier League goal, and in a difficult game, so I'm very happy.
"There were a lot of beautiful goals, I think it was a difficult day for the goalkeepers. When I received the ball, I saw Luke (Shaw) coming on my left and I was going to give him the ball but it was so nicely on my right foot, I thought I would shoot.
"I'd been practising in training yesterday with Granty (Lee Grant) and it gave me a lot of confidence as I put four in the top corner from exactly the same range.
"So I had a good feeling and I went for it. It's amazing. You feel a lot of emotions and I'm very happy and hopefully there will be many more to come."
