The 34-year-old Blues academy product has returned to the club on a free transfer following his Newcastle departure, signing a two-year deal at Fratton Park.

Well, thanks to @SonStats - a PFSA Level 2 technical scout and performance analyst, plus an avid Pompey fan - we’ve been given a clearer indication.

4. Areas for development
