As usual, Rangers and Celtic are planted firmly atop of the Scottish Premier League table. Through six rounds of play, both teams have won five games and slipped up once. Rangers are currently top, the difference between the two teams being one draw for Rangers and one loss for Celtic. They should be first and second by some distance at the end of the season, and they should finish fairly close together. So despite the fact that this game is taking place in September, it's one of the biggest games of the year for the title race in Scotland.
Of course, it would be one of the biggest matches of the year no matter what. If both teams were mid-table with little chance at going down or winning the title, the Old Firm Derby would still be the Old Firm Derby. Even if the teams are no longer the European contenders they were just a short time ago, it's still one of the biggest matches in world football.
Both teams should be close to full fitness, giving the two managers plenty to choose from when picking their teams. Scott Brown and Anthony Stokes sat out in the Europa League mid-week for Celtic, but could be fit enough to make the bench. Other than that, the teams have a clean bill of health.
Celtic and Rangers have forwards in good form, midfielders who can score goals, and defenses that have allowed a combined three goals between them in the Scottish Premier League this season. But, there's no way to know how good these players really are and what their form really means until they face off against each other.
Rangers vs. Celtic kicks off at 7:30 am ET, 12:30 pm local time on Sunday from the Ibrox Stadium in Glasgow, Scotland.
