Premier League wives and girlfriends (WAGS) have warned their partners to avoid taking language classes with football language teacher Sara Duque.

The 27-year-old football language coach is causing controversy for her gorgeous looks. The brunette bombshell counts Man City and winner Julian Alvarez as one of her successful students.

“From lifting the World Cup to conquering a new language- my student's talent knows no bounds!” read her caption on the post with Alvarez.

“Impressive progress in such a short period of time. Very proud of my student!”

She also teaches Brazilian midfielder Arthur Melo, who joined Liverpool on loan from Juventus last summer.

Duque is fluent in an impressive six languages: Portuguese, English, German, French, and Spanish.

But while footballers have given her credit for improving their speaking skills, the WAGS are far more concerned about her services.

How Sara Duque became off-limits

Before starting her language learning service tailored for footballers, Duque became a lawyer in .

Itching to get involved in football, she ditched legal practice and obtained her Master's degree in Sports Psychology and Mental Coaching at the renowned Real Madrid Graduate School in .

She continued sports medicine study in the United States before trying her luck at FC as a football language coach. Now, she's willing to strike out on her own as a private teacher for Premier League's foreign players.

All the while, Duque has grown her Instagram account to a whopping 160k followers. She wows her following with a series of bikini-clad selfie snaps, and sexy gym poses.

Despite the red card from Premier League WAGs to drop her as a teacher, we don't think Duque will be hanging up the job any time soon.

On the contrary, this could be the start of many more recruits.
