Everything has changed at Arsenal since Unai Emery replaced Arsene Wenger in May.
The Spaniard has brought in his own coaching team, released fan favourites Jack Wilshere and Santi Cazorla, and signed no less than five players.
A huge season awaits the Gunners and it will be interesting to see if Wenger leaving really was the best move for them.
Pressure will be high on the players to deliver but there's a sense that a lot of the focus will be on one man in particular - Mesut Ozil.
Ozil, who recently inherited the No.10 jersey, was poor at the World Cup for Germany and will need to step up his game for the upcoming campaign.
He at least has the support of his new manager, with Emery saying recently that he's looking forward to working with the divisive 29-year-old.
"We are here to help every player," said Emery. "For us Mesut is a very important player. We want to help [him].
BIG SEASON AHEAD
"The [Germany] national team didn't get the results they want but today he is on holiday, and I want him to relax well and I want, when he comes back with us, to start with a good mentality.
"I want to work with him with a new way and with an ambition to continue with this quality and to help him to get better with the team."
Because of his involvement at the World Cup, Ozil wasn't expected to return to pre-season training until Arsenal's tour of Singapore on July 22.
However, according to Goal's Chris Wheatley, the German has cut short his holidays and already returned to London Colney - and the reason why is fantastic.
Ozil has been in regular contact with his Arsenal teammates since returning from the World Cup and hearing about the quality of Emery's training sessions has convinced him to start early.
Clearly Ozil is very excited to start working with his new manager and doesn't want to waste any more time.
And that's nothing but great news for Arsenal fans. Ozil has been a decent signing for them - he was phenomenal in 2015/16 - but Wenger never quite got the best out of him.
But with Emery now in charge and making such a good impression, there's every chance Ozil could finally realise his true potential at the Emirates Stadium.
