Parkinson saw his side stun Aston Villa 4-3 on aggregate after a 2-1 defeat at Villa Park on Tuesday night to reach next month's Capital One Cup final. He said: "I think it'd take some doing for anyone to do this again.
"We had a really tough run. It wasn't just the Premier League teams, we had tough games with Notts County and Watford too." Bradford went into the second-leg at Villa Park 3-1 up but Christian Benteke reduced the deficit for Villa. James Hanson headed Bradford level on the night before Andreas Weimann scored a late goal for Villa. Parkinson's side started their run to the final with an away tie at Notts County the week before the league campaign started in August. En route to the final, the League Two side have seen off the Magpies, Watford, Burton and Premier League sides Wigan, Arsenal and now Villa. Their date at Wembley is the first time they have reached the final of a major competition since winning the FA Cup in 1911 and the first time a side from the fourth division has made the final since Rochdale in 1962. Parkinson believes the money earned by the run to the final will secure the future of the club - as well as the place of his side in the history books.
