I agree completely. Even if he's our captain, I actually don't think he's good enough. Sure, he scores a nice goal sometimes, but now that we want to compete in the Champions League, I think our midfield captain ought to be better.
I don't know who Keita is and don't know who else could replace him, but I would like for it to happen.
So basically you just want Henderson replaced no matter what?
Fans tend to be fickle, but to not remember how well Henderson performed before his injury (and how it reflected on stats as well, most passes) is not even fickle, it's straight up case of utter amnesia.
And you people never learn, you did the same to him when Klopp came in and he couldn't train due to injury, so you watched us suddenly play with more intensity, and quickly implied Henderson won't be able to walk into this side, let alone be one of its best players. Then he recovered, walked into the side and bossed the midfield again and again. He's still our best midfielder, you know? No amounts of overhead kicks from Emre "I don't really know how to create chances" Can can (feck) change that.
Another player that gets tons of people moaning about how we need to buy a replacement, is Clyne, and honestly at first I thought people were having a laugh slagging him off, but then I realised that's because the fans don't really look at defence, ever. Fans' critique comes from watching us attack, so there's very little admiration for someone that simply does his job and keeps his mouth shut about it. Clyne is not the problem, whoever plays on the right wing, tends to be the problem. The right side of defence is solid in comparison to the clinically dead Lovren-Milner combo, not to mention Clyne is less wasteful in his passing and duels he takes on than Milner on the other side. He is also not the kinda player who would lose his temper, his play is patient despite him probably hearing the moans from the stands every time he is trying to get some composure and make sure he's covered at the back, before foolishly dancing into the box, losing the ball and then seeing the lower-tier shithouses score on the counter. The last two sentences apply to Milner's style of fullback play, btw.
In any case, you people won't realise what you have until it's gone, especially in case of Clyne, the most reliable and defensively solid right-back we've had in pretty much decades at this point. I understand the Henderson critique because he's injury prone and it's not that hard to forget about him, but Clyne critics are football equivalents of flat earth society.
