Manchester United goalkeeper Edwin Van der Sar bemoaned his side's bad luck after being knocked out of the FA Cup by neighbours Manchester City.
Yaya Toure's second half goal was enough to send City through to the final at Wembley after countless missed opportunities for United.
And the Dutch goalkeeper believes had early chances been taken, the result would have been very difficult.
"We started a bit slow but had two chances in quick succession," he told MUTV.
"If one of those goes in, maybe it's a different game and they would have to chase us.
"In the second half, when they scored, we went to 10 men and it was hard to chase and try to get the equaliser. We had some half-chances or possibilities to get the ball into the box but nothing really materialised. We were hoping for that famous injury-time goal again but I think our luck ran out a little bit.
"It's always nicer when you score first but that didn't happen and the goal we conceded was a bit scrappy. It's not the way we normally defend so we have to do something to take the blame - all the players who have been on the pitch. Nobody really performed to their standard I think. So we need to make sure we do better on Tuesday."
With a six point gap now separating themselves from Arsenal at the top of the Barclays Premier League, United can extend their lead as they travel of Newcastle United on Tuesday night, as they look to make amends for their derby defeat.
