Maybe the crucial call comes today.

The 21-year-old has been linked to a transfer this summer, while Leverkusen seeks 100m euros for his services, Periscopi broadcasts.

Chelsea is the main favourite to secure his services, but the director of Leverkusen, Simon Rolfes, insisted that the club has not yet received any official offer.

However, asked whether Harveytz has made the decision, Bosz has said: “I cannot say. Maybe the cruise call comes today, maybe next week, maybe it doesn't come at all. ”

Harveytz has scored 17 goals and eight assistings for Leverkusen's campaign. /Periscope. com/
