Atalanta have rejected a €25 million ($26 million) offer from Chelsea for Franck Kessie.
Kessie's agent claims there's also interest from Liverpool, Manchester United, Manchester City and Arsenal.
Kessie, who spent last season on loan at Cesena, has been in outstanding form as Atalanta have risen up to sixth place in Serie A after 18 games. Kessie has drawn comparisons to Yaya Toure.
Chelsea are keen to find a replacement for the Brazil international Oscar, who completed his move to Chinese Super league side Shanghai SIPG for £52 million this week.
