ARSENAL have begun their pre-season training at the state-of-the-art Adidas facility in Germany.

The ‘Arena’ was opened by the sportswear company almost three years ago in Herzogenaurach, and it has now opened its doors to the Gunners.

The £850 million building has a soccer field and a state-of-the-art gym with yoga and CrossFit classes.

Additionally, there are tennis and basketball courts, a running track, and bouldering climbing walls on the property.

In addition to a swimming pool and a beach volleyball court, Arsenal players will have access to them so they may relax after practices.

5,600 people work on the site, and the ‘Arena’ has a futuristic design that makes it look like it is floating in the air.

The three levels of this building, whose construction cost above £350 million, are made up of “retreat-like rooms” and open spaces.

Up to 2,000 meals can be served at the company restaurant each day, and there are meeting spaces modeled after sports fields, one of which has artificial turf.

Arsenal have made use of the facilities ahead of their match against Nurnberg on Thursday.

Mikel Arteta and Martin Odegaard were spotted playing a game of keepy-uppy alongside a member of the coaching team, and the Gunners boss showed he has not lost his touch.
