'Special' double for Williams
Swansea captain Ashley Williams still classes an away game against Manchester United as a special occasion for visiting players.
Williams and Swansea are preparing for back-to-back games at Old Trafford, with a Premier League away fixture following on from Sunday's FA Cup third-round tie.
United have already lost four times at home this season under new boss David Moyes, but Williams does not believe a trip to the Premier League champions has got any easier as Swansea look to end a run of seven games without a win in all competitions.
"It's an important game as we haven't won in so long, but going to Old Trafford is a special occasion for any footballer and we will go there," said the Wales defender.
"We will try and enjoy it and we will try and put a few things right.
"I think they are a top class side, there are no worries about United as far as I am concerned.
"With the transition with the new manager things can take time and it was going to be tough. But they still have a lot of the same players from last season and they can play a number of their players in their squad who are world class."
