Sir Alex Ferguson was pleased to see his side maintain their lead in the Premier League but he knows there is a long way to go before the champions are crowned in May.
United returned to the top of the league courtesy of their win over QPR at the weekend and a 1-0 victory against West Ham keeps them one point clear of neighbours Manchester City, who defeated Wigan at the DW Stadium.
It would appear to be advantage Manchester in the title race with United and City extending their lead over Chelsea, who were held to a 0-0 draw by Fulham.
"Tonight's results have drawn us away from Chelsea a little bit further. We're still ahead in the league but City are on our tails and it's going to be a long season,” he told the Sun.
Although the title could down to goal difference, Ferguson has stressed the importance of winning by the narrowest of margins and he will happily accept 1-0 victories.
"The importance of winning 1-0 in certain games is that your opponents know the resilience is there," he went on.
"If you look at some of the really important 1-0s we've had... go back to beating Newcastle when they were nine points clear of us in 1996 our 1-0 that night won us the league.
"There are important 1-0 victories. We've had many of them."
