The Bantams’ recent knockout heroics had made them narrow favourites to book their place in the semi-finals for the first time since 1911, despite the fact they faced higher league opposition.
But after watching Gary Liddle come closest when he hit the woodwork late in the first half, Parkinson was keen to revive the siege mentality which helped them to wins over Chelsea and Sunderland.
Parkinson said: “We will go down there for the replay as the underdogs and we will approach it in a positive fashion because we’re at our best when we do that. We won at Stamford Bridge which was seen as a day out for us because no-one expected us to go and get a result. So we are still alive and kicking.”
Pavel Pogrebnyak and Oliver Norwood also hit the post for Reading, bidding to reach the last four themselves for the first time since 1927.
Steve Clarke’s men know they may never have a better chance than the replay, scheduled for next Monday at the Madejski Stadium.
