Manchester United defender Rio Ferdinand says no attention has turned to Manchester City's end of season toils.
City have won one of their last three, and have surrendered a five-point lead to United at the top of the table.
United have meanwhile won six on the spin in the Premier League, the latest three-points coming virtue of a tight victory over Fulham, the type of win Ferdinand believes will gift them the title.
"I've been in that [City's] position before," Ferdinand said.
"I remember playing at West Ham a few years ago when we went out for the warm-up. Everton were winning 2-1 against Chelsea and when we came in we found out it had been reversed.
"Chelsea won the game and it killed us a little bit and we ended up losing to West Ham that time. So, yes, psychologically it can affect teams but we don't care what happens with them, it's about us. If we remain calm and win all our games, we'll be successful.
"Ideally we'd like to have played better football but it wasn't to be. Fulham had a game plan, they set their stall out to frustrate us and did that for long periods but in the end, after a couple of crosses, we got the ball in the back of the net.
"You've got to hold your nerve but as important as that, if not more important, is trusting each other. You've got to trust in the fact that if you're not going to create a chance, someone else is. If you're not going to put your head on the ball when it comes into the box or make that tackle, someone else is.
"That's the way you've got to be and the team that does that best between now and the end of the season will be the one to win the league."
United were lucky to claim victory over Fulham, with Michael Carrick fortunate not to concede a penalty in the closing minutes after clumsily challenging Danny Murphy, a decision City will find tough to accept.
After beating Chelsea last week, City stumbled to a draw against Stoke City, needing Yaya Toure's deflected strike from range late on to escape with a point.
However, Ferdinand says United must not become fixated on City's results between now and the end of the season.
"It doesn't really bother me to be honest," Ferdinand added.
"As long as we keep winning our games, that's all that matters. Instead of worrying about the other teams and how they're doing, it doesn't really play on our minds to be honest.
"It's about us, about keeping our own house in order. We say the same thing every season but it really is true."
