I don't think he should be captain and I also don't think he should be guaranteed a first-team position. He's one of the most hardworking midfielder's in the premier league, which is why I still think he should be a squad player, but if we are to challenge for titles he doesn't have footballing intelligence or skills to lead trophies. I'm sure things will change with the introduction of Keita.
I agree, Henderson is a decent player and we have enough games that he should be playing in the squad, but he shouldn't be captain, we should be bringing in better quality players, like we are with Keita, which then force out players like Henderson.
