Celtic fans have voiced their disappointment as the Hoops trail Hearts 1-0 at half-time.
It's been a tough contest at Tynescastle for Ange Postecoglou 's men who have struggled to trouble Craig Gordon so far.
Gary Mackay-Steven took the lead for the home side on eight minutes with little in the way of a comeback since for the Hoops.
Twitter user @67_Celtic_1888 said: "Hearts have a formation & a game plan....We are void of both....Hard to watch. This side spent last season in the CHAMPIONSHIP."
@SinkyCeltic added: "Hearts aren’t struggling anywhere on the park here. We are working hard and players are getting tired."
One fan remarked: "Going to be a long season" while another said: "Celtic absolutely honking, Hibs finishing second fact."
More blame has shifted towards the board as @mxtt188 tweets Celtic: "You needed this to realise you need a new back line and a goalie? Board need to get the finger out."
Martin Coyle said: "So far I’m seeing shades of last season plenty of the ball no end product mistake from starfelt but can’t place blame boys just in need to be more direct second half come on Celtic."
