Sir Alex Ferguson still does not believe there is any fixture in the Premier League calendar like Manchester United against Liverpool.

The north-west giants go head-to-head at Old Trafford on Sunday both eager for points as well as bragging rights after less than perfect starts to the season.

It is bound to be a keenly contested affair, despite the fact Liverpool's wait for a 19th league title has now been extended to an incredible 20 years.

"I sound like a parrot but this is the fixture. There is no question about that," Ferguson said.

"It doesn't change. The form fluctuates quite a bit but we won the last game so hopefully that turns it back towards us again."
