John Mousinho on the 'pivotal' figure driving Portsmouth promotion bid - and he last played a decade ago

While many were surprised at John Mousinho’s appointment as the Blues’ head coach, similarly the rookie boss’ choice of a 43-year-old right-hand man also raised eyebrows.

Arriving after a decade in Chelsea’s Academy, Jon Harley’s February employment represented a return to Fratton Park following a short-lived playing spell.

Having attended the same Uefa Pro Licence course at St George's Park, Mousinho had put the ex-Chelsea, Fulham and West Ham left-back’s name forward as a potential contender as assistant head coach.
