Hello and welcome to LIVE comments from this FA Cup fourth round clash between Aston Villa and Birmingham at Villa Park

Ciaran Clark flashes a header goalward only to see the ball blocked by Salgado as Villa continue to push forward and keep Rovers on the back-foot. Even more concerningly for the visitors Roque Santa Cruz is looking like he will have to be replaced as he signals to the dug-out

Rovers are beginning to settle in on this clash now as Salgado just misses to the right of the goal with his shot from the right of the penalty area

The hosts fails to make nothing of their corner as Bannan fails to get his shot on target and Rovers escape with Robinson gettign a free goal kick

Villa draw the first corner of the day as Emile Heskey draws a block from Grant Hanley off his shot just to the right of the penalty spot

Ooof. Great start by Villa as Barry Bannan picks up the ball on the left before firing a shot goalward from about 25 yards out. He misses just to the side of the right post but Robinson didn't look all that confident about that one

We're underway at Villa Park ...

It's not exactly packed at Villa Park today although in fairness to the fans it is absolutely freezing in Birmingham today!

BLACKBURN meanwhile look like this: Robinson, Salgado, Samba, Hanley, Olsson, Nzonzi, Andrews, Pedersen, Hoilett, Roberts, Santa Cruz. Subs: Bunn, Jermaine Jones, Kalinic, El-Hadji Diouf, Grella, Mwaruwari, Lowe.

Right, the teams are in and ASTON VILLA line up like this: Friedel, Walker, Cuellar, Clark, Baker, Pires, Reo-Coker, Bannan, Agbonlahor, Heskey, Delfouneso; Subs: Marshall, Downing, Ashley Young, Albrighton, Delph, Petrov, Collins

With John Carew having joined Stoke on loan, Emile Heskey is set to return to the starting line-up. Ciaran Clark (hamstring), Fabian Delph (knee) and Kyle Walker (back) are all available again. But Luke Young and Stephen Ireland are both still sidelined with knee injuries.

Villa's record signing, Darren Bent, is cup-tied for today's clash. Bent, who signed from Sunderland for £18 million, played and scored for the Black Cats when beaten by Notts County in the previous round.
