West Ham United boss Avram Grant admits their 4-0 thumping of Manchester United in the Carling Cup was "unbelievable".
Jonathan Spector and Carlton Cole scored two goals each as United crashed to their heaviest defeat since 2001 and their first loss of the season.
The Hammers are in the semi-final finals of the League Cup for the first time in over 20 years and Grant hopes the result can help inspire a move out of the Barclays Premier League relegation zone.
"I thought we could win but this is still an unbelievable result. We continue our progress," he said.
"We scored four goals and could have scored more. But for me four is enough.
"To be in the semi-finals is very good for this club. We are trying to build something step by step. We have done the right thing.
"We have played many more good games without winning so the players maybe have lost confidence.
"But the most important is to show mental strength and tonight was so unbelievable.
"The gap at the bottom of the Premier League was five points and is now three points.
"We have many games left and I'm sure that this shows we can be good in the future."
