Unai Emery is just days away from taking charge of his first Premier League game.
The Spanish manager took charge of Arsenal just a few months ago as Arsene Wenger's replacement.
He has been extremely active in the transfer market, with Lucas Torreira, Bernd Leno, Stephan Lichtsteiner, Sokratis Papastathopoulos and Matteo Guendouzi all arriving.
Arsenal fans will be hoping he can get off to a good start when his side host Manchester City on Sunday.
But how have Arsenal been preparing for the new season?
Arsenal's director of high performance, Darren Burgess, has provided an insight into Arsenal's training in pre-season.
And Burgess has revealed that Emery has been particularly focused on improving their defence before the start of the Premier League campaign.
“Most people recognised that our defence was poor last season," he said, per the Evening Standard.
"We conceded a ridiculous number of goals, which Arsenal hadn’t done in maybe 35 years, so one thing [Emery] has been working on is making the team better organised in that area.
“It remains to be seen how successful that is but that’s an area he’s focused on.
"He’s very particular on player positioning, depending on where the ball is in certain areas of the pitch. His sessions are very intricate in that regard."
That will come as good news to Arsenal fans.
Arsenal have got some extremely talented players in attack. With the likes of Pierre-Emerick Aubameyang, Alexandre Lacazette and Mesut Ozil; Arsenal have one of the best attacks in the league.
But one of the biggest issues for Arsenal in recent years have been their defence.
For example, last season they has the joint third best attack in the Premier League with 74 goals, but they only had the eighth best defence, having conceded 51 times.
It's obvious that their defence held them back from greater success last season, and it's been a problem which has been ongoing for some time.
If Emery is successful in transforming Arsenal's defence, they could well challenge for the Premier League again next season.
Burgess also gave an insight to how Emery operates as a manager.
“Like Arsene [Wenger], he’s a workaholic: he’s always watching film of training or the opposition. He’s never not analysing, even in the lead up to friendly games.
"He’s unbelievably passionate and the training sessions are extremely up tempo and full of instructions and hands on.
"He’s passionate about playing football a certain way and he really wants Arsenal to play that way. It’s been great getting to know him.”
