The striker missed the FA Cup tie with Reading due to a sinus problem but has been a key figure during the chase for glory on three fronts. In an exclusive Google+ DHL hang-out with Jonny Evans and Tom Cleverley, Rooney revealed the key to the side's splendid form.
"I think it's consistency," he replied when asked to explain why the Reds are riding so high at the summit. "We've been the most consistent team.
"Obviously, it's put us in a great position as, when other teams have dropped points, we've managed to keep winning or not lose too many games.
"I think the team spirit and desire to win all comes from the manager, who has been in place here for 26 years. So the players all know what we have to do and we all want to win.
"We all want to do it together, whether you're starting or a substitute or, sometimes, are not even on the bench. There is no bitterness between the players. We all want to work together and win together."
