The England international failed to fire on all cylinders in Sunday's 1-1 draw at the Liberty Stadium, proving uncharacteristically wasteful in possession and ineffective in front of goal.
Wayne Rooney: "I could feel it (was not going to be my day) on the pitch.
"Some days you have an off day I could feel that and I couldn't complain at being substituted.
"I think the thing about football, and especially over the Christmas period, is that you have games and this game has gone for me and it is certainly not one I will remember, but I will relish the next one.
"The position we are in at the minute, it is a great opportunity to make that gap at the top of the table even bigger.
"We are still in a good position with two home games coming up.
"We need to make sure we take maximum points from them. We know it's early days and there is a long way to go, but we are in a healthy position at the moment so we need to try and keep on.
"It was good to see him (Nemanja Vidic) get 90 minutes.
"He has been out for a while and he has been working hard in the gym and at the training ground.
"He did well at Swansea and he will be a massive player for us between now and the end of the season.
"He is a great defender and great to have in the team and a great leader. We have a few players in the team who can lead from the back or the front and he is our captain and does that."
