Sir Alex Ferguson has begun the mind games with Chelsea this season by claiming that they have had such an easy start, they should have won every game.
The Blues have romped to the top of the Barclays Premier League after winning all but one match so far this term, with their only setback a defeat at Manchester City.
But United boss Ferguson, whose side slipped five points behind the champions at the weekend following a goalless game at Sunderland, has suggested they should have a 100% record.
Asked if the Red Devils could not afford to drop any more points, Ferguson said: "No, no, no. Every team is going to drop points - that's inevitable.
"If you look at Chelsea's start to the season, you'd have expected them to have won all those games, so the position they're in doesn't surprise me.
"Meanwhile, we've had tricky trips to Fulham and Everton then played Liverpool at home. Those are difficult matches. Liverpool, Arsenal and ourselves have all played top sides early on. Chelsea's sterner tests are still to come."
