What a chance for former Hearts man Avdijaj.
A cross finds the forward in space at the back post but he can't put his header on target.

Up the other end, Avdijaj is in acres of space off the left and sees a strike crucially blocked by Kye Rowles.
The resulting corner is nodded over by Selnæs. Hearts needing to dig in a bit.

From defending that corner, Barrie McKay dribbles the ball back to Gorgie and wins his side a free-kick on the way.
Excellent stuff from the Hearts winger.

Just getting pictures of Craig Halkett making his way to the bench on crutches. Not good.
Meanwhile, Hearts deal with a corner... just about.

Quote MessageIt's been a strange game. Zurich started well and made a few chances, and out of nowhere Hearts get the penalty. Lawrence Shankland sticks it away and everything is rosy. And then they collapse. It's two really poor goals to concede.
HT: FC Zurich 2-1 Hearts
Hearts' passing accuracy is down at 79% for that first half, and it drops to 57% in the Zurich half. It's 53% for the final third.
They'll need to tighten up if they want to make more of an impact in front of goal in the second half.

Quote MessageI think those two Zurich goals possibly don't happen with Halkett on the pitch. He's a big, big miss for Hearts.

Quote MessageOver the piece, 2-1 down at half-time is by no means a disaster for Hearts.
After a promising Hearts start which saw Lawrence Shankland bag an opener from the spot, the visitors briefly collapsed as Zurich replied with a quickfire double.
Still scope for Robbie Neilson's men to take a decent result back to Tynecastle.

Sensational stuff from Barrie McKay.
He makes something out of nothing by dancing past two men and rolling the ball across the edge of the box.
Jorge Grant picks it up and tries a reverse shot into the bottom corner. Keeper gets there easy enough.

Hearts need a breather. Clear heads. Deep breaths.
