Villa ran out 2-0 winners against the Baggies before chaotic scenes which saw fans invading the Villa Park pitch, with the majority riding the wave of elation which was produced as a result of the win.
“To captain such a huge club to Wembley is an amazing feeling,” said Delph.
“We certainly have a lot of confidence in the camp. Overall it was a big chance to get to Wembley and there was no way we weren't going to do it.”
It’s important Aston Villa boss Tim Sherwood boxes up the positive feeling created by the win over the weekend and uses it to the club’s advantage, as they look to improve their position in the Premier League.
Villa are by no means clear of trouble in terms of the relegation scrap so they need to savour and cash in on any advantage they can build over the rest of the season.
The occasion of a semi-final at Wembley should also inspire Aston Villa’s players to put some pressure on Tim Sherwood in terms of his squad selection.
The next few weeks are a great opportunity for all players to make a statement of their intent and a chance to force their way into the side to perform on the platform of Wembley.
Next up for Villa is a match against Sunderland this weekend and after a week of rest, the side should have a spring in their step produced by the confidence Delph talks about.
