Eduardas Kurskis is consoled at full time at Ibrox

"I feel for him," said Frail after Kurskis allowed Lee McCulloch's shot squirm over the line in the 2-1 defeat.

"He is distraught in the dressing-room and so are the rest of his team-mates.

"We didn't get at them like we wanted and lost a scrappy goal, but the second half was a marked improvement and we were a totally different team."

Interview: Hearts coach Stephen Frail

Frail was trying to look beyond the immediate disappointment of the defeat at Ibrox.

I thought our two centre-halves were immense Hearts assistant boss Stephen Frail

"After we equalised, I thought we could have gone on to win it," he said.

"But I have to take the positives out of a totally depressing end to the game.

"We sat them down at half-time and told them to have the belief that they could beat Rangers, just like they did against Celtic.

"They showed that in the second half and I thought our two centre-halves were immense."

Frail also picked out winger Andrew Driver for praise.
