VfB Stuttgart are set to reward Filip Kostic with an improved contact according to reports from Bild.

It is believed that Stuttgart are willing to pay the talented 23-year-old winger upwards of €37,000-per-week in a bid to ward off interested clubs.

Liverpool have been linked with the Serbian international while a host of Italian clubs are also believed to be keen.

But Stuttgart are intent on keeping the former FC Groningen wide man, who comes with a transfer fee of around €20million and is contracted until the summer of 2019, and will reportedly increase his wages to €150,000-a-month.

Kostic, who arrived at the Mercedes-Benz Arena in the summer of 2014, has scored three goals and provided four assists in 17 Bundesliga outings this season.
