With 36 English titles between them, Premier League games don't get much bigger than Manchester United against Liverpool.
The two North West giants continue their intense rivalry at Old Trafford on Sunday in a fixture that always serves to make the heart beat a little faster for supporters of both sides.
The backdrop to this encounter involves a season which has barely got underway but has already had its fair share of drama for the two teams.
United have already fallen four points behind defending champions Chelsea after throwing away winning positions to draw in away games against Fulham and Everton, while Sir Alex Ferguson’s side also had a below-par night against Rangers in the Champions League.
Liverpool have a new manager, Roy Hodgson, who has made a mixed start as the Reds look to recover from last season’s disastrous seventh place finish which eventually led to the departure of Rafael Benitez to Inter.
Admittedly Hodgson’s charges have had a very difficult run of fixtures to open the new campaign, along with European commitments to be balanced, but defeat on Sunday would mean an unsatisfactory return of one win from five league games.
Therefore the pressure is on for the new man at the helm to pick up some sort of result at Old Trafford in a game the significance of which his opposite number knows all too well.
Ferguson – who once famously said his aim at United was to knock Liverpool off their perch at the top of the domestic game – used his pre-match press conference to re-iterate just how big the game is.
"I sound like a parrot but this is 'the fixture'. There is no question about that," he asserted.
"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.
"Roy has the experience. He has gathered a wealth of experience in Italy, Switzerland and Finland and the job he did at Fulham was absolutely extraordinary.
"But our approach will not change. We have to express ourselves the way we always do.”
A win in front of their own fans will certainly be the target for United, although they will be wary of their fierce rivals.
Liverpool have tasted victory in three of the last four games in the head-to-head, although the last meeting saw the Red Devils win 2-1 thanks to a winning goal from Ji-Sung Park.
Whatever the result on Sunday there is sure to be incident, with the final result potentially significant in setting up a positive or negative season ahead for either side.

Prediction
Manchester United have dropped needless points in recent league games against Fulham and Everton, while the midweek draw with Rangers did little to improve the mood at Old Trafford.
Liverpool have had a very tough run of fixtures at the start of the season, but they would certainly have hoped for better than just one win from their domestic games so far.
The formbook usually goes out of the window in games between these two bitter enemies, which makes predicting a tough ask, but I'm backing the home side to edge a victory here.
