West Brom manager Gary Megson couldn't hide his disappointment at going out of this season's FA Cup.
Having watched his side put in a solid performance against the Whites. The Baggies were undone by set-piece. And as Megson revealed, it's not the first time that's happened this season.
"We played well and put on a good show but it matters not a jot if you can't defend set-pieces.
"It is that that has cost us the chance of a semi-final appearance and possibly about 10 points this season. That is our Achilles heel."
The nature of the goal made the loss particularly hard to swallow; yet Megson still remained courteous in defeat.
"If one of their players had knocked it in from 35 yards or beaten a few players to score we'd accept that is the quality of their side.
"But it wasn't a game like that and it came down to a free-kick that settled the game and we didn't defend it properly.
"They have got some exceptional players and I hope they go on to do well in the cup because there is some solace in losing to the team that wins it.
"We couldn't have worked any harder and we made a Premiership team defend very hard for the last 40 minutes but when games are tight it can come down to a mistake."
