The striker has struck eight times in La Liga this season – a tally that is only bettered by Lionel Messi and Valencia's Simone Zaza.
Bakambu's form has unsurprisingly not gone unnoticed and, according to Marca, he is now being tracked by Newcastle, West Brom and West Ham.
The Hammers are said to have been interested in the 26-year-old in the summer but their bid of around £20m was knocked back.
Villarreal are very reluctant to sell their star striker and that stance is unlikely to change in Janaury.
But, their hand could be forced if one of Newcastle, West Brom or West Ham submit an offer too good to refuse.
