The Cameroonian ace is currently away from Loftus Road on a season-long loan with Sevilla, where he has been impressive.
His consistent displays have alerted the Merseyside duo, who are both said to be looking to add a robust midfield man to their squads ahead of next season.
Despite only joining the Super Hoops in early 2013, Mbia is unlikely to return to West London even if the club gain promotion back to the top tier with his desire to test himself at the highest level strong.
Liverpool are known to be keen to add a player of the 27-year-old’s qualities to their ranks, with Lucas’ injury having revealed a lack of depth in their midfield.
Everton are also looking at the tough-tackling star, with Gareth Barry’s loan stint at Goodison Park due to end in six months’ time.
Sevilla are thought to be looking into keeping Mbia permanently, but it’s unlikely that they will be able to compete with the English sides in a financial sense.
