Birmingham City v Huddersfield Town: Have Town learnt their lesson against Gary Rowett's resolute side and other key questions

Huddersfield Town travel to Birmingham City this weekend knowing a defeat would be the first time in 15 years they have lost four times on the spin since the 2000/2001 campaign, when they were relegated from the second tier.

A similar scenario seems an unlikely prospect given the points difference between Town and third bottom Wigan Athletic, but it would serve to underline the downturn of form Town have suffered in recent weeks.

And now they face a side in the Blues who, after a minor blip of their own, are all of a sudden riding on the crest of a wave under Gary Rowett once more, after back-to-back 1-0 home wins over Brentford and Blackpool respectively and a late, late comeback draw at Derby County.

But what are the key questions for Town ahead of the trip to St Andrew's?

Here are just some things to think about as Powell's side look to put a nightmare week behind them and ease any fears of being dragged into the relegation dogfight.

Have Town learnt their lessons from the reverse meeting?

Rowett was handed something of a poisoned chalice when he arrived at Birmingham off the back of their record 8-0 home defeat to a rampant Bournemouth outfit, but he has moulded a side who looked destined for a season of woe when he inherited them to a competitive and resilient unit.

The Blues have flourished defensively under a former stopper and the fact they have conceded more than one goal at home only twice since his appointment is testament to the work he has carried out on a backline which was previously leaking goals.

Those two matches came against West Bromwich Albion (1-2) in the FA Cup and Derby County (0-4) in the anomaly from an otherwise consistent run of home form so Town face a difficult task in breaking down an obdurate defence.

That was illustrated best when the Blues came to the John Smith's Stadium before Christmas, shut up shop and absorbed all the pressure before pouncing in a smash-and-grab raid style performance.

The onus will be on Birmingham to come out and play the football slightly more here, but Rowett will prioritise resolve over taking the game completely to Town, so the Terriers must show both patience and courage to break down the hosts' rearguard because the odd goal could settle the contest once more.

Will potential returns hand Town a timely fillip?

Town boss Chris Powell was understandably keen to keep his cards close to his chest regarding injury news at his pre-match press conference, but he was pressed into revealing that Harry Bunn will be ready for a return against the Blues.

Bunn, a self-confessed champion of playing away from home, can expect an instant recall and most probably in place of Joe Lolley, despite the youngster providing some spark and excitement to Town's play during last weekend's wretched display at home to Rotherham United.

He could potentially replace Sean Scannell if the Town boss fancies mixing things up with both Lolley and Bunn in his side, but the returning wideman will hope to carry on where he left off on a personal note after a wonderful goal against Brentford.

Less assured of a place in the starting XI, or the matchday squad - for that matter, is Nahki Wells, whose absence has coincided with three defeats from three since suffering a shoulder injury against Reading.

It has been a frustrating stop-start beginning to 2015 for the Bermudian, but Powell has conceded his side have missed his movement up front and so don't rule out the prospect of a return if he can get up to speed quickly, as Town badly need a response.

Can the midfield trio rediscover their fluidity?

One of the other factors behind Town's recent struggles has been the lack of cohesion to their midfield unit, which has chopped, changed and suffered as a result.

Against Charlton Athletic, Bunn was deployed at No.10 with Jonathan Hogg and Jacob Butterfield in behind and the system failed to click, while at Brentford it was David Edgar who came in as the defensive shield but to no avail.

Then, Powell reverted to type by bringing Conor Coady back from the cold after a three-match absence from the starting XI against Rotherham, but even that alteration failed to bring about the desired change in fortunes for Town, who were lacklustre throughout.

Town have been at their best this season when their layered midfield trio of Hogg (defensive destroyer), Coady (driving force) and Butterfield (creator in chief) have worked in tandem and how Town could do with each of them rediscovering their best form tomorrow.

Hogg's return to the side has failed to provide Town with the energy and industry Powell would have anticipated, while he has been vocal in his thoughts on Coady's recent performances and Butterfield has looked reliant on his midfield partners while the chips have been down, so each must carry out their roles to offer more balance and structure in the middle.
