Lukas Jutkiewicz is the target for a long Birmingham ball forwards. Moments later, Che Adams is fouled and Birmingham have a free-kick.

Dan Clinton: Gabby Agbonlahor still useful for (perhaps only) one thing at least!

Simon Atkins: So much for the optimism! We can still get back into this, been playing well, just need that one good chance!

By the way, that substitution means the two Gardner brothers, Craig and Gary, are on opposite sides of the field at the same time.

Villa bring on Gary Gardner for Albert Adomah in midfield.

Villa's Nathan Baker does well to get a head in to block Jacques Maghoma's cross, which was aimed towards Lukas Jutkiewicz.

At the other end, Alan Hutton does well to clear for Villa. Then keeper Sam Johnstone does well to turn round the post moments later. Corner to Birmingham.

The goal came from Villa's first shot on target, from their first corner of the game.

Gabby Agbonlahor hadn't scored in 14 months, since scoring in one of Villa's rare Premier League wins last season against Norwich.

Prior to that, he hadn't netted in 11 months.

But he does know how to score in derby games, having done so too often in the past for Blues fans' comfort.

He scored the first of his five derby goals in Steve Bruce's final game in charge of Blues in November 2007. And Bruce brought him back from the cold to come off the bench when the two sides drew 1-1 at St Andrew's in October.

Now Bruce has turned to him again... and he has provided!

The game has really livened up since the hour mark.

But still no goals.

David Davis has a snap shot for Birmingham in the area from nothing, but Sam Johnstone saves for Villa with his fingertips. Good stop.

James Chester rises highest to meet the Villa free-kick but heads over the bar. It was a good ball in.

Now Birmingham's Ryan Shotton and Villa's Gabby Agbonlahor are having something of a scrap.

Villa have a free-kick in a dangerous position, near the corner flag.

Both Shotton and Agbonlahor are booked.

Gabby Agbonlahor quickly wins a throw in and the Villa fans roar with approval. His arrival has given them a lift.

Striker Gabby Agbonlahor comes on for Villa, replacing Jack Grealish.

That sees Villa switch to two up front.

Villa's Alan Hutton finds Albert Adomah, whose cross is cleared.

Now Hutton and David Davis clash in the middle and the referee steps in to calm things down.

Simon Atkins: Optimistic. Blues to win 1-0, and to prove that we just needed competent leadership! 

Birmingham fans seem impressed so far. Whoever you support, you can get involved via #bbcefl on Twitter.

To remind you, Harry Redknapp took over a struggling Birmingham side that hasn't won in nine games before today.

He'll be happy with their improvements so far, but it remains goalless.

Henri Lansbury badly overhits an attempted through ball and Birmingham have a goal kick.
