Phil Parkinson's side produced a famous 3-1 win at Valley Parade in the first leg, but face an improving Premier League outfit for a place in the Capital One Cup showpiece

Aston Villa need goals, so Brett Holman could return in a more attacking line-up than the one that featured at the Hawthorns on Saturday, with Gabriel Agbonlahor continuing to partner Christian Benteke up front.
Fabian Delph (knock) is a doubt for Villa after going off injured against West Brom, with Barry Bannan waiting in the wings should the former Leeds midfielder fail to regain match fitness.
Nathan Baker (leg) was also replaced against the Baggies and is likely to miss out, while Andreas Weimann will hope to recover from the illness that kept him on the sidelines at the weekend.
Phil Parkinson made wholesale changes for last Tuesday's Football League Trophy defeat against Crewe, and those rested for that fixture should return to the line-up for this Capital One Cup semi-final second leg.
New signing Michael Nelson could feature in defence for Bradford, while recent addition Andy Gray is ineligible after appearing for Leeds earlier in the competition.
Top goalscorer James Hanson should return after missing the last two games with a broken toe, while Stephen Darby (foot), Will Atkinson (stomach) and Garry Thompson (knee) are also all in contention.
