VAR is here but Robbie Neilson is only worried about landing a rousing result. Fiorentina made light work of them, however, last Sunday's meek efforts in their loss to Aberdeen was the performance which had punters demanding more.
And now Neilson must find a solution to stop Ange Postecoglou 's Celtic from becoming the latest team to put the hurt on Hearts this season. The Premiership champions don't take a backwards step and are aiming for all three points in the capital ahead of their Champions League clash with Shakhtar.
Gorgie often comes alive on days like these and Hearts need their fans to help inspire them to a result against Celtic. They managed it last season on the opening day, however, Postecoglou's side is unrecognisable to the one who came up short on that occasion.
Edinburgh has never been a city short on performance art and expect plenty of drama to coincide with the new technology which is being rolled out across the top flight this weekend.
Hearts: Gordon, M.Smith, Kingsley, Kio, Devlin, McKay, Cochrane, Sibbick, Humphrys, Ginnelly, Snodgrass
Subs: Stewart, Clark, Grant, Shankland, Halliday, Forest, Neilson, Henderson, C.Smith
Celtic: Hart, Ralston, Carter-Vickers, Jenz, Bernabei, Mooy, O'Riley, Hatate, Forrest, Maeda, Giakoumakis
Subs: Siegrist, Taylor, Kyogo, Haksabanovic, Abada, McCarthy, Ideguchi, Abildgaard, Juranovic
