Ibrox will stage a game between second and third in the Scottish Premiership

Given that Hearts are proving so impossibly stubborn at the top of the Scottish Premiership, refusing, it seems, to do what is expected of them by the old order and kindly going away, the pressure returns to Rangers and Celtic in Sunday's must-win to end all must-wins.

Martin O'Neill turns 74 on the day. What better way to spend it than in the furnace of the Old Firm. Candles on the cake won't concern him. Points on the board will be the only thing on his mind. A draw is of little use to either club now.

This game demands a winner and if there is a winner there has to be a loser. Heaven help them. The wrath will descend, especially if it's Celtic, you suspect. It's not like Rangers folk will shrug in defeat - it's not exactly their style - but Celtic fans are an angrier and more frustrated crew right now.
