Manchester United will travel to Wales to play a Premier League match for the first time when they visit Liberty Stadium to face Swansea this Saturday.
Swansea are making their debut in the Premier League this season and have impressed thus far, lying 10th in the league table after 11 games while showing that they are willing to open up and attack their opponents.
They host defending champions Manchester United after their 0-0 draw at Anfield a fortnight ago, and will be hoping to get points off the Red Devils as well.
Fletcher is wary of the threat Swansea pose, and has revealed that he has been keeping an eye on the Welsh team.
"It's a new experience for us all. They're the first Welsh team in the Premier League and going there will be a great experience," Fletcher told his club's official website.
"Swansea have been applauded for the football they've played this season. When I was on international duty, I spoke to a couple of my Scotland team-mates who have played against them and they told me how well Swansea keep the ball.
"They play football in the right way and have been a breath of fresh air since coming into the Premier League," he continued. "It's going to be a real challenge for us on Saturday.
"I'm sure this is the sort of fixture Swansea and their fans have been dreaming about for years. Welsh fans are always passionate and I'm sure the stadium will be packed out so it should be a fantastic atmosphere."
