Avram Grant believes West Ham deserve to land a first Wembley appearance in 30 years - but he warned his men that will count for nothing against Birmingham.
The Hammers take a 2-1 lead into their Carling Cup semi-final second leg at St Andrew's, having knocked out Sunderland and Stoke and thumped Manchester United 4-0.
West Ham's last Wembley appearance was in 1981, also in the League Cup final, where they drew 1-1 with Liverpool only to lose in the replay at Villa Park.
Grant said: "To be at Wembley after such a long time would be very good and, if I may say it, we deserve it. Our route to this game has been very good. We won the first game (against Oxford) in the last minute.
"We played very well to beat Sunderland away, we showed a lot of character against Stoke and we were brilliant against Manchester United. That is the only game they have lost all season. But we know that no-one will give us any presents. It will mean a lot also to Birmingham - but for us it is very important.
"We have a good record in the cups this season and it has also been good football. We have scored a lot of goals and we want to continue like that. There is one more game to the final."
