The 19-year-old French ace has been heavily linked with the Blues in recent weeks, with rumours suggesting that the London club are locked in a battle with Inter Milan and Monaco for his services.
Zouma is considered to be one of the very best young players in Europe, and has already established himself as a first-team regular at the famed Ligue 1 side despite his youthful age.
Jose Mourinho is said to be a big fan of the teenager, as he plots to bolster his defensive options to keep his side in the title race.
Zouma’s agent, Alexandre Bonnefond, says that he is talking with a big side from England, which is speculated to be Chelsea:
“Some big clubs are interested in signing Kurt,” he is quoted by The Metro.
“There are some talks with teams from Italy, France and especially England.”
Zouma is valued at around £13m by Saint Etienne, who have shown in recent times that they are willing to sell their star names after allowing Pierre-Emerick Aubameyang to join Borussia Dortmund.
