We pick the ten worst-value signings of all time.

No.10 - Juan Sebastian Veron
Manchester United paid a whopping £28.1m for Argentinian midfielder Veron and he soon became a target for the Old Trafford boo boys - standing as he did in the centre of midfield and not achieving a great deal. Sir Alex Ferguson once said to the press: "He's a f***ing great player, you are all f***ing idiots", before selling him to Chelsea for £15m.
