"I could feel it on the pitch that things weren't right at Swansea," Rooney told the Daily Mail.
"Some days you have an off day I could feel that and I couldn't complain at being substituted.
"But the good thing I think about football, and especially over the Christmas period, is that you have lots of games and the Swansea game has gone for me and it is certainly not one I will remember."
The Red Devils were top of the table for Christmas with a four-point lead over rivals Manchester City but the 27-year-old is confident that they can continue to increase the gap.
"The position we are in at the minute, it is a great opportunity to make that gap even bigger between us and Manchester City at the top of the league," he continued.
"Obviously against Swansea we couldn't do it but, as I say, hopefully we will get six points from the next two games and see what happens."
