They say that familiarity breeds contempt, but in the case of Celtic and Rangers this almost seems like an understatement.
Last season saw an unprecedented seven Old Firm derbies in all competitions and the animosity between the two sides has scarcely been greater.
On and off-field tensions dominated the headlines during the 2010-11 campaign, but everyone will be hoping that the attention turns to the football again on Sunday as the Glasgow rivals head into the first derby game of this term.
For the first time since taking charge of Celtic, Neil Lennon goes into an Old Firm game as the more experienced of the two managers and Celtic are 39/20 with bwin to take advantage of this with a win at Ibrox on Sunday.
Ally McCoist has a wealth of Old Firm experience both as a player and as an assistant, but this will be his first derby as Rangers manager and he can be backed to lead Rangers to a debut victory at 7/5.
The sides met three times at Ibrox last year, with two of the games ending in a draw, and another tie this time around is priced at an attractive 21/10.
Celtic scored in all but one of the derbies last season and with new signing Mo Bangura challenging the prolific Anthony Stokes and Gary Hooper for a starting berth up front, the Bhoys will be confident of finding the net again this weekend.
The visitors can be backed at 7/4 to score more than 1.5 goals in the match, 13/4 to score in both halves and 6/5 to score the first goal of the game.
Rangers are sweating over the fitness of star striker Nikica Jelavic but can take comfort from the goalscoring form of Kyle Lafferty and Stevie Naismith.
Lafferty scored his second goal in only three league games last Saturday against Dundee United, while Naismith has five for club and country already this season.
The Gers can be backed at 5/2 to score in both halves, while they are 13/2 to score twice before half-time and 22/25 to open the scoring.
With both teams looking dangerous going forward, the game will almost certainly hinge on which side can defend better under pressure.
Both Rangers and Celtic have kept clean sheets in five of their opening six SPL matches and both sides have conceded only one goal each – maintaining this record could be the key to victory on Sunday.
Rangers are 14/5 to win the game to nil, while Celtic are 4/1 to do likewise. But with both teams posing such a potent threat in attack, goals could certainly be the order of the day.
