Andreas Pereira says he's more than capable of handling the rigours of the Premier League.
The 23-year-old has been given more responsibility by Ole Gunnar Solskjaer this season.
Pereira insists he's happy at Old Trafford and ready to help his team win matches.
"I feel very confident and very happy.," he told the club's website.
"The manager gave me a lot of confidence, and the staff as well, so I feel very happy and very strong.
"I feel mature. I've played a lot of games and I'm a different type of player now and I'm ready for what's coming next."
