Is this the secret to Alexis Sanchez's fitness?

Is it any wonder Alexis Sanchez is settling in at Arsenal so seamlessly?

The Chilean international shared a rare photo on his Twitter feed last night, showing him relaxing at home with his indoor swimming pool.

That is of course what his reported £150,000 per week salary will buy, and it's clear he intends to use it to keep his fitness up and recuperate after a matchday. It beats watching Tottenham on ITV4, right?

It was only a day earlier the £30 million summer signing had scored a superb goal as the Gunners beat Dortmund 2-0 at The Emirates, his third goal in five games.

He is already looking like a bargain, described by former striker Ian Wright as the club's 'saviour', keeping them in the hunt for success after their recent mixed form.
