And he has been supported by beautiful Wag Isabella Rousso, who seemingly doesn’t miss a game he plays.

The 21-year-old blonde med student joined her beau on Mikel Arteta’s side’s US preseason tour this summer.

While she is a regular at the Emirates Stadium – always wearing her trusty Arsenal shirt with Martinelli’s name and number on the back.

Gorgeous Isabella regularly shares her life in the lab on her Instagram stories to her 184,000 followers.

And when she’s not, she’s living the life every Wag enjoys.

Travelling around the globe is clearly very important to Isabella.

In the summer, Martinelli and Isabella visited their homeland – where they spent time on the amazing Brazilian island of Fernando de Noronha.

The pair also enjoyed some time in Dubai, where they got the obligatory picture in front of the Burj Al Arab.

But, there’s a certain venue that’s certainly got her heart.

Sightseeing around London is fun for Isabella.

However, there’s one place she’s regularly seen at in the N7 area.

The South American is a mad Arsenal fan – often seen modelling the team’s kits.

She shared a photo on social media wearing a home shirt with Martinelli’s name and number on the back.

The photo was captioned: “My love written on my back.”
