THERE are certain non-negotiables if you want to play for Celtic, and those count doubly if you want to win a Premiership title. You must be relentless in your pursuit of success, and you must be resilient when that success looks to be slipping away.
Celtic have shown both of those qualities this season, and their manager Ange Postecoglou saw plenty of evidence of that as his team dug out the draw they needed against Rangers to inch themselves closer to a remarkable title triumph.
