Stoke City boss Michael O'Neill was left frustrated after their FA Cup defeat to Crystal Palace.
Stoke pushed Palace all the way before losing 2-1.
O'Neill said, "At the very least [we deserved to go to extra time]. I think for a period in the second half we were the better team. There was very little in the first half.
"The first goal wasn't a corner. We have all the technology to see if it's a goal. Having seen it back, the Palace player's shot doesn't come off James Chester. We felt harshly done by.
"At 1-1 we looked the team more likely to win. Unfortunately we can't defend the corner. It lands to the feet of their lad. It comes through a crowd of bodies and ends in the bottom corner and that's why we're out of the cup.
"The attitude was fantastic. The quality of our play was fantastic. I don't think you'd have seen a big difference between the sides."
On Joachim Andersen's goalline clearance: "The lad did brilliant to get back. It would have put us 2-1 ahead. Those are the margins between winning and losing.
"I'll watch the game back and see things we can improve on. Maybe we turned the ball over a bit too much.
"We know where we are, we have a lot still to work on but we're a team going in the right direction."
