Hearts goalkeeper Marian Kello had a superb game against Rangers but could not prevent his side squandering a one-goal lead.
Steven Naismith won it for the champions late on, and Kello was almost inconsolable.
He said: "I wanted to cry at the final whistle. It was very painful.
"I had some good saves but the result is very disappointing and I'm very unhappy that we lost the game."
