Crunch time for Heckingbottom and Levein as they aim to rejuvenate Edinburgh rivals
As the tension and excitement heightens in Glasgow at the prospect of a league title battle between Celtic and Rangers, along the road in Edinburgh it's a different story.
Hibernian manager Paul Heckingbottom and Craig Levein of Hearts have had testing starts to their respective seasons with just one league win between them so far and tomorrow's derby clash at Easter Road is huge for both.
Many have billed this game as a public audition for both to preserve their jobs.
Played out in front of a full house and live on TV, it will be survival of the bravest.
It does seem extremely early in the season to be thinking along these lines but supporters of Hibs and Hearts are very demanding and expect to be challenging at the top end of the table as opposed to being where they currently sit.
Hearts are bottom of the Scottish Premiership and city rivals Hibs occupy ninth place.
This is way below what was predicted for both managers and both sets of players in the summer ahead of the big kick-off.
So in the shadow of the famous hill in the capital, Arthur's Seat, at 3pm tomorrow, it will be telling which manager can get the best out of their players and start their own climb up the table.
