Henderson is the clear favourite for me.
From the current squad it has to be Henderson for me too
The thing is we have a young squad so there aren't that many clear stand outs beyond him.
I don't agree with this hiding thing some are accusing him of, he very rarely hides.. That shouldn't be confused with having poor games but all players do.. He is someone always encouraging his team mates, talking to them, bollocking them when needed.. He is the main one that the manager talks to to get tactical instructions on the pitch.. He has a good understanding of the game, he wears the armband when he has this season with that sense of leadership.
He may not be an obvious choice like a Gerrard was or a Carra, Hyypia in recent times but within this young squad we lack those types.
If you look at the other options.
Sakho. Looks a leader and has at PSG and France but hasn't established himself here fully yet and hasn't cracked the language fully yet
Skrtel. Needs to fully concentrate on his own game to me to be at his best, not a natural leader and the added distraction wouldn't help his game. A possible vice captain within the current squad but for me isn't what we should really be looking at as captain
Lucas. Depends on his future, has respect of the players I think but it depends on his long term future, I don't think his legs means he starts every game either so again for me more a vice captain rather than the main man.
Lallana. Saw him mentioned but not been at the club long enough to be considered. I also think there was more a chance he captained Southampton with the length of his time there and respect he held due to that rather than being such a stand out leader he can become the leader of a club like ours having only been here 6 months
Lovren. Far too much to prove yet
Flanagan. Needs to establish himself longer term yet before he gets into these conversations.
Toure. No long term future at the club where we are so can't be considered.
So for me where we currently stand in this squad
Henderson Captain
Lucas Vice (if he stays)
If Lucas moved on I'd take a punt on Sakho as vice and build the back line round him
