Huddersfield Town's first-team squad are currently in Marbella stepping up preparations for the new season at a week's training camp, which will culminate in a friendly against Leyton Orient on Saturday.

This is the second full week of training since returning to PPG Canalside on July 1 and one friendly is already out the way, with a convincing 3-1 win at AFC Guiseley secured courtesy of goals from Nahki Wells, Jacob Butterfield and Joe Lolley.

But what are the main talking points from Town's pre-season so far?

Take a look at our five observations made on the Terriers' work to date as the big kick-off at Hull City on Saturday, August 8 inches ever closer.

The 3-4-3 experiment

Could Chris Powell be about to stumble upon a formation which suits his needs by accident rather than design?

He admitted after Saturday's triumph at Nethermoor that his use of Tommy Smith and Jack Senior on the sides of an unconventional midfield four was born out of necessity due to absentees, but it may solve the defensive issues Town had last season.

Powell admitted he would look to trial different formations during pre-season and it is unlikely that he will settle on the system after one positive performance against the Vanarama National League outfit.

But it certainly offers him food for thought as he looks to eradicate the flaws in the rearguard from last term.

Butterfield starting as he left off

It was a fitting end to an excellent first season at the club when Butterfield scooped the club's player of the year prize and, if his cameo against Guiseley was anything to go by, he looks raring to go for 2015/16.

He oozed quality once more, spraying passes around with ease and constantly looking for the darting runs in behind of Sean Scannell on the right, a combination which served Town so well last season.

He capped his first performance back as the most recognised midfield face with a goal epitomising all of his best qualities, with an excellent pass out wide initially followed by the awareness to follow the ball in before an expert first touch, shimmy and finish.

Butterfield looked fresh, confident and determined too on Saturday, indicating that he can reach even greater levels with Town this season.

Lolley proving his point once more

The nimble winger found the back of the net in Town's penultimate game of 2014/15 at home to Blackburn Rovers and if he continues to do so, as he did at Guiseley, he will give Powell something to think about.

Like Butterfield, his goal was symbolic of everything Lolley's game stands for, with a trademark burst down the touchline accompanied by a dribble inside his marker and a quite sumptuous finish into the far top corner.

With Sean Scannell and Harry Bunn the likely established first-choice duo out wide, Lolley will have to use this as a springboard for upcoming friendlies, but he is very much in his manager's thinking.

His performance at Guiseley will have done him no harm at all in boosting his first-team chances.

The youngsters are getting a chance

With injuries to the likes of James Vaughan, Jonathan Hogg and Philip Billing, Powell was forced to bring in some of the club's young talents for the trip to Nethermoor at the weekend, with Jack Senior the most notable inclusion.

While the likes of Lloyd Allinson, William Boyle, Joe Wilkinson, Billing, Duane Holmes and Jake Charles are considered part of the first-team picture, Senior's presence, particularly from the start, suggests Powell is looking at various options open to him having shown faith in the 18-year-old - who was part of the U18 squad who reached the Professional Development League 2 play-off semi finals.

The 18-year-old gave an encouraging display to suggest he can cope with the step up, with Powell also offering a host of others to showcase their potential and ability to adjust, with Boyle benefiting from being involved in both halves alongside Holmes and Bunn.

Powell will have been impressed by what he saw from several of his starlets but is also offering opportunities to the likes of Adam Hammill, whose future has been up in the air, and trialist Martin Cranie too as he looks to fine-tune his squad.

Things will get tougher

It may sound obvious, but the intensity of Saturday's game was so one-paced against the Vanarama National League outfit that it was difficult to escape the belief that the level of training will only get tougher for the players in the next week.

The calibre in opposition will improve in the build-up to the new campaign and so the trip to Marbella this week will be far more gruelling, particularly given the weather conditions, than the work to date.

Powell signalled as much in the immediate aftermath of Saturday's game: “That was the positive game we needed, so now we’ll go out to Spain and look to kick things on a notch out there.”

Town will come face-to-face with League Two side Leyton Orient as well as League One duo Rochdale and Barnsley either side of the much-anticipated home clash with Deportivo de La Coruna, which will serve as better indicators of where Town are headed in 2015/16.
