Sir Alex Ferguson has admitted his surprise that Manchester United have hit the top of the Premier League table at this point in the season.
United replaced Liverpool at the top of the table after Saturday's narrow 1-0 victory at Bolton Wanderers.
But Ferguson has been surprised by their rise to the summit so soon after returning from the Club World Cup in Japan last month which left them playing catch up with two games in hand on their rivals.
"We're a bit surprised about how things have turned round since we got back from Japan," he told MUTV.
"But at the same time we know it's a very difficult league and any team can drop points anywhere. That's the beauty of the English game.
"Being top is not decisive at this stage, but it's always nice because it's the best place to be."
Meanwhile, Ferguson has warned his players against complacency with 17 league fixtures still remaining this season.
"We've been playing catch-up in terms of fixtures for a while now," he added.
"We took advantage of our first game in hand against Wigan and we've got another to come at home to Fulham next month.
"Only after that will we have a good idea of where things stand between Liverpool, Chelsea and ourselves."
