Bayer Leverkusen’s sporting director Rudi Voller insists the club have not given up hope of keeping Kai Havertz after Chelsea opened talks to sign the midfielder. Acording to reports on Tuesday, Frank Lampard’s side have begun negotiations with Leverkusen over a potential deal for the 20-year-old this summer. Havertz is widely regarded as one of the best young midfielders in Europe and has attracted strong interest from both Manchester United and Liverpool, as well as Real Madrid and Barcelona. However, when asked about Havertz’s situation on Tuesday evening, Voller claimed that Leverkusen are ‘in a good position’ and predicted that speculation will increase ‘if he plays like this now’.
