Huddersfield Town face a second trip to London on Tuesday night to face play-off chasers Brentford determined to bounce back from the disappointment of losing 3-0 at Charlton Athletic at the weekend.

It was not the return to The Valley Chris Powell had in mind as his charges failed to get going and were blown away by the speed of the Addicks on the counter attack as Johann Berg Gudmundsson's long-range free-kick and a Tony Watt brace did the damage.

The reverse to Guy Luzon's side was, however, the first time Town have tasted defeat on the road in four games and indeed only the second time in 2015 altogether, so Powell will hope to yield a response from his players against Mark Warburton's high-flyers, particularly having already beaten the Bees this season.

But what are the key questions for Town ahead of their trip to Griffin Park?

Here are just some things to think about as Chris Powell's side aim for their third double of the campaign after Millwall and Reading.

How do you fix a problem like Powell's defensive one?

Town fans' biggest disappointment on Saturday was that their team never really looked like backing up what was an impressive result by the same 3-0 scoreline against Reading, as inconsistency came back to haunt them once more.

The most consistent feature of this side has been the defensive woes they have suffered all season long and, though there were recent signs that they had overcome that.

Judging by the painful evidence on Saturday, there are still flaws at the back which need ironing out and their goals conceded column (56) still ranks as the third-worst tally in the division, behind Fulham (58) and basement boys Blackpool (68).

That amounts to 1.7 goals conceded per game on average and emphasises how important their efforts at the other end of the field have been throughout the course of the season, with only the Cottagers (46) - whose goal difference mirrors Town's - scoring more goals than Town outside the top nine teams.

With a front four of Jota, Alex Pritchard, Jon Toral and Andre Gray to keep quiet, the trip to Griffin Park is daunting enough as it is, let alone off the back of a 3-0 defeat and don't be surprised to see Tommy Smith come in for David Edgar, who was poor on Saturday, as a result.

Will the midfield setup change?

Powell was probably right to persist with a formation that paid dividends against Reading at The Valley as he targeted a quick start to silence the raucous home faithful.

He spoke about a desire for an early goal in the build-up to the clash and kept faith in Harry Bunn at the apex of midfield, with Jacob Butterfield and Jonathan Hogg in support and he looked for a defensive and offensive balance on either side in Sean Scannell and Jack Robinson.

The majority of the blame may have been laid at the feet of the back three but the midfield department were also due some criticism for failing to track runners or offer any sort of support to a backline completely outpaced and stretched by Charlton's lively strikeforce of Igor Vetokele and Tony Watt.

It wasn't until the introduction of Conor Coady early in the second half that Town were able to realise any sort of energy at either end of the field but it was sadly a case of too little, too late at that point.

Bunn may be the player most at risk of dropping from the XI for Coady if Powell wants more of a rigid defensive structure, and he would surely achieve that with three in midfield, but don't rule out the prospect of one up front again because the 4-5-1 shape used in the 1-1 draw at Bournemouth recently was perfect in nullifying the passing game of a top side, something Town will have to do once more tomorrow night.

Will Town concede possession to their hosts?

It has been one of the most detectable correlations in Town's stop-start beginning to 2015, how their share of possession impacts on results.

In the simplest terms, the Terriers have more often than not found themselves on the winning side when they have relinquished the ball to their opponents and have only come out on top in games where they have had the lion's share of play twice - against relegation-haunted duo Millwall and Blackpool.

That in itself should underline that Town are still learning, still adapting and still establishing themselves at Championship level, reflected in their current mid-table position and an inconsistency which is paralleled by so many other sides in this division.

They enjoyed more of the ball once again on Saturday, but failed to really convert their possession into anything threatening in the final third and, with such an attack-minded lineup, they were picked off by a vibrant Charlton side.

If, as expected, Powell urges more caution at Griffin Park, it will surely result in the hosts dictating the tempo of the game but Town must be patient against a side whose game relies on midfield technicians such as Pritchard to feed Gray and inverted widemen Toral and Jota.
