Bohemians v Shamrock Rovers, Dalymount Park, (7.45): Deeply frustrated with his team's performance for much of Friday's third round clash with city rivals Bohemians, manager Pat Scully has called on his Shamrock Rovers players to stand up and be counted ahead of tonight's FAI Carlsberg Cup replay at Dalymount Park.

A youthful Rovers were swept off the park in the opening half against a Bohemians side who themselves may well feel disappointed not to have been more than 1-0 ahead at the break.

But Rovers emerged rejuvenated in the second period and Tadgh Purcell's penalty levelled the game.  Indeed such was their dominance that Rovers could have sneaked a winner late on but David Cassidy squandered a superb opportunity.

"I was very disappointed as we didn't perform at all," says Scully.  "In the first half we were awful, absolutely awful. It was completely unacceptable but the players don't need me to tell them that, they know it themselves.

"Second half we stood up to them at lot more but still we didn't play spectacularly well.  We managed to get the penalty back and then worked extremely hard."

Scully concedes his side must improve ten-fold to overturn a stubborn Bohemians in their own backyard.

But he pin-pointed his squad's 'never say die' attitude and believes Rovers have nothing to fear from their opponents should they replicate, if not improve on, last week's second half showing.

"The atmosphere of these derby games is new to some of the lads but when you taste an atmosphere like that you can either hide or stand up and fight.

"We have nothing to fear. I didn't fear anything last Friday and I won't tonight. It's a game of football. Go out, stand up for yourself and let yourself be counted. That's what we'll be doing tonight."

Scully's counterpart, Gareth Farrelly, was also disappointed with Friday's outcome but for different reasons.

A week earlier his side showed tremendous courage and belief to beat Shelbourne but Farrelly was frustrated that his players failed to mirror that drive against Rovers.

"We knew what to expect from Rovers but we've a young squad and sometimes you have to keep hitting home the message.  Sometimes we're a little naïve," he says.

"For all the good football we play, sometimes we don't do the simple things well and if that happens you leave yourself open to punishment."

Farrelly came off the bench in the second half but is in line for a starting role tonight having overcome hamstring trouble and a bout of flu. Defender Jason McGuinness returns from suspension.

With so many players cup-tied, Rovers' squad is severely stretched so Scully will pray midfielder Vinny Perth (foot) and winger Jamie Duffy (calf) overcome late fitness tests.
