Further to the above, numerous living players have had statues erected to them (Stanley Matthews was alive when the Hanley statue was unveiled though not the Britannia Stadium one; likewise Hugh McIlmoyle at Carlisle, George Hardwick at Middlesbrough and more).
Henry is the only UK-based player to have still been playing when his statue was unveiled: however Johann Cruyff (Holland, Olympic Stadium), Blaise Nkufo (at Twente Enschede, Holland) and Gabriel Batistuta (Fiorentina, Italy) were all still playing when unveiled. Alex Ferguson will no doubt still be managing when his statue is unveiled at Old Trafford this summer.
