Fernandes joined the Red Devils last month in a deal worth around £46.6 million after spending three years in the Primeira Liga with Sporting CP.
The Portuguese has made a seamless transition to English football as he scored his second goal for Manchester United in their 5-0 win against Club Brugge in the Europa League on Thursday night.
Scholes is confident Fernandes will maintain his current form and insists the 25-year-old has already transformed his former club into an exciting side.
"It was a perfect night for Manchester United and there were a lot of very good performances. Fernandes stood out and he controlled the pace of play," the 45-year-old told BT Sport.
"He looks like he has brought this team to life. He has made a team that did not look that watchable at times look exciting and very watchable right now.”
"When you bring in a player like Fernandes it livens everyone up. Usually a player from a different country takes more time. Hopefully, he stays in this form for the rest of the season.”
"What do I like about Bruno? Everything so far. Creativity. His awareness on the pitch. Before the ball comes to him he knows what's around him.”
“He's sensational — you just wonder why nobody else came in for him or why we didn't get him in the summer."
