Arturo Vidal and Alexis Sanchez showed off their physiques at Inter Milan training

With Inter looking to secure their first Serie A title in a decade, the decision was made to allow the veterans to remain in Milan and get their fitness levels up for the final part of the season.

Neither man certainly seemed to be suffering from the intense workout, with both flashing wide grins while Sanchez, 32, gave a thumbs up to the camera.

Vidal, 33, captioned the picture on Instagram: “Preparing for what is coming stronger and stronger with my bro.”

And it drew a reaction from fans, with one writing: “Perfection in one photo.”

Another said: “Chilean football machines.”

And a final one added: “When you win the Scudetto, please take Sanchez to the tattoo studio.”

Despite their absence for their country this week, Vidal and Sanchez will be sure to return to action with Chile for June’s World Cup qualifier with Argentina.

Vidal has amassed an incredible 119 caps for his country.

And Sanchez has even more with 136 appearances – making him Chile’s all-time leading man.

The Copa America winners are close buddies, having first played together at Chilean side Colo-Colo between 2006 and 2007.

They both went their separate ways after, with Vidal turning out for Bayer Leverkusen, Juventus, Bayern Munich and Barcelona.

Meanwhile, Sanchez’s career saw him take in spells at River Plate, Udinese, Barcelona, Arsenal and Manchester United.

But they were reunited at club level when Vidal joined Inter last summer thanks to efforts from his former Juve boss, Antonio Conte.

And both men have been in superb form, with Vidal making 23 league appearances and Sanchez playing 20 times.

Inter are six points clear of nearest challengers AC Milan at the top of Serie A.

And they can extend that lead to nine as they still have a game in hand to play.
