Mat Ryan has expressed his sympathy for opposite number David Morrow after Brighton & Hove Albion beat Millwall in the FA Cup quarter-finals.
Brighton edged Millwall on penalties to book their place in the semi-finals at Wembley against Manchester City.
The Lions led 2-0 before the Seagulls scored twice to tie up.
Morrow was at fault for the second goal, when he let Solly March's free-kick slip through his hands and into the net.
Ryan felt bad for the rival keeper.
"I approached him after the game, it happens," the Australian told The Mirror.
"Just after half-time there was a mix-up between Shane [Duffy] and I, thankfully we mopped it up. Unfortunately, he probably looks at that one and thinks he probably could have done better.
"I told him that one moment does not define him. He was solid all game apart from that. He seemed to have plenty of character himself. You have got to learn from your mistakes and see what you can do to not let it happen again.
"Aside from that he had a great game and I am sure he will be better of his experience."
Ryan made a crucial penalty save to help Brighton into the final four.
