All I know Owen is second captain if Becks gets out to play, say it's should've him inherited the armband automatically. Poor Owen's recent injury makes him to taking a rest for not contributing in following England's fixtures. At the time, McLaren's already made his decision who will England skipper replacement to be.
I'd say either Terry or Gerrard.
Terry ---- is a leader character, spirit icon for The Blues. His (yelling) contribution to maintain back-to-back Chelski's consecutive title was second to none, and as defender he's got the upper hand to looking/reading the game freely on pitch battle ahead.
Gerrard --- Since took over the armband from Hyypia at Pool, Stevie G is vital figure and has always been a saviour at critical times happened. These both FA Cup and CL 2006 trophies were ocular proof into his name.

If you love to see Gary Neville's actions at ManU, you could pick him as England skipper then.
