Double change for Blues. Jacques Maghoma and Clayton Donaldson are replaced by Viv Solomon-Otabor and Nicolai Brock-Madsen.

Villa almost double their lead but Jordan Ayew's dangerous ball across the box goes past everyone and out for a goal kick.

Villa's Ashley Westwood is booked for holding onto the ball for too long.

Tomasz Kuszczak dives to his right to palm away Scott Sinclair's free-kick. That wasn't a bad effort from the Villa man.

Michael Morrison is booked for pulling back Jack Grealish after he had skipped past him. Simple one for the referee. Villa have a free-kick.

Huge chance for Blues to equalise but Jacques Maghoma can't beat Brad Guzan. The winger beat the offside trap to race onto Demarai Gray's neat through ball into the area but his left-footed effort was too close to the keeper, and didn't have enough power on it. Was that Birmingham's moment?

Birmingham have responded reasonably well and things are a bit more even again, since that Villa goal. But it is the visitors who have to make things happen now, not Villa.

Maikel Kieftenbeld's misplaced ball back to the goalkeeper gifts Villa a corner. Villa can't capitalise though, as the set-piece comes to nothing.

Demarai Gray has a pop from outside the area but his shot swings wide of the right post. That was better from Birmingham, though.

Villa's Jack Grealish skips his way to the byline but the ball goes out for a goal kick. He wants a corner, but it isn't given.

Jon Toral, on loan from Arsenal, comes on for Birmingham's David Davis. That's an attacking switch from Gary Rowett, as Toral will sit just behind Clayton Donaldson up top.

Villa have been made to work hard for that opening goal, but they have a breakthrough at last. Could that end up being the winner tonight? Or will Birmingham respond?

Jacques Maghoma's delivery goes over everyone in the penalty area and Birmingham have to start again with a throw-in on the half-way line.

Time is ticking by in this second half and we are still waiting for the first goal. The noise picks up another notch. Can Birmingham withstand this Villa spell? The hosts still haven't created many clear-cut chances, despite their improvements since the break.
