Frank Lampard was excused from reporting for the start of pre-season training by Derby County as he finalises his return to Chelsea as head coach.

Chelsea hope to formally announce Lampard’s appointment in the next 48 hours, following productive talks, with Blues players due to start reporting for pre-season later this week.

Lampard had been willing to start pre-season with Derby, but the club decided it was better for him and the players that he concluded talks with Chelsea.

In a statement, Derby acknowledged the fact that talks over the weekend between Lampard and Chelsea had been productive and that an agreement is now imminent.

The statement said: “Derby County Football Club has excused Frank Lampard from reporting back for pre-season training on Monday and Tuesday to allow his discussions regarding a potential move to Chelsea to be concluded as soon as possible.

“The first few days of pre-season training will be focused on fitness training and will continue as planned under the guidance of the fitness, medical, conditioning and sports science teams at the club’s Training Centre.

“On the assumption that Frank will reach an agreement with Chelsea to become their new manager, the club shall step up its efforts to find a replacement manager.”
