Michael Carrick's coaching career at Manchester United is already mirroring his playing days - unassuming but highly influential.
Carrick, who returns to his first club West Ham on Sunday, was regarded by Sir Alex Ferguson as a pivotal part of his second Champions League-winning team even though Cristiano Ronaldo and Wayne Rooney took the glory.
