Robbie Neilson knows the tough test that Hearts face against Celtic as he outlined the one key attribute his team must show.
The Jambos head for Glasgow full of confidence after a convincing win over St Johnstone to banish the pain of that defeat to Motherwell at Fir Park.

The midweek Parkhead clash is the first of two between the sides this week with Ange Postecoglou taking his troops to Gorgie on Saturday lunchtime. The pair go head to head in the Scottish Cup quarter-final with a spot in the last four and a trip to Hampden up for grabs. But before any attentions turn to that big occasion, it is league duty first with Neilson aware of the 'different challenge' his side face.
