Arsenal star Martinelli's stunning Wag is medical student Isabella Rousso

GABRIEL MARTINELLI has the backing of Arsenal fans, and his stunning girlfriend.

The Brazilian forward has been in sensational form for the Gunners - helping his side's march to the top of the table.

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.

Honeymoon period

Although it's not known how Martinelli and Rousso met, reports suggest they've only been dating for under a year.

She is originally from Rio de Janeiro and is studying medicine.

Gorgeous Isabella regularly shares her life in the lab on her Instagram stories to her 44,000 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.

Emirates regular

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."

Another shows Rousso pitch side - writing "35" with a red and white emoji. 35 is, of course, former squad number.

With three league goals this season, Martinelli has already given Isabella plenty to shout about.

Maybe, though, she needs this season's home strip.
