I'd say the jury is still out on both Hendo and Jonjo. Can't see either coming into contention for the captaincy within two or three years, not even sure they will both still be at the club! Edit: and I'm a fan of both too
Hendo will be long gone, **** like that will flush away in the transfer window. Kelly or Cody for Captain...keep it local!
If Gerrard steps down/becomes less of a permanent fixture within the next 2 years then I think Lucas will get it. However if he continues for a little longer then I'd say Jonjo is a dead cert providing he can keep improving.
