It particularly affects the goal keeper.
If he has a flaky centre half in front of him, he can see the mistakes coming a mile off, through bad positioning, getting caught flat etc and the keeper ends up concentrating on “ when “ the centre half is going to make a mistake, as well everything else that’s going on.
Many blamed Pickford the other night (I don't see it as his fault). Keane wasn't playing in that game...
I just think our partnerships look stronger when it's Keane and one other.
Against Leicester we kept them quiet. They didn't do a thing. It was one cock up - Keane's howler - that they capitalised on. But on the whole, had that game finished 0-0, we'd probably have been saying both Keane and Zouma had a solid game, because they did up until that point.
Evans made an equally as bad of an error at the other end, for example, by passing straight to Tosun. But Tosun isn't Vardy, unfortunately for us.
I like Mina, I think he's our 'best' defender. He has strength, a bit of pace and aerially he's strong. He does like to run out and dive in, though, which is something that Zouma does a lot of. I'd say out of the three of them, Keane has learned to stand his man more (not saying he doesn't make errors, as he does), and in that one example I'd say that it's important to have one player who is more aggressive, and one who is more conservative.
Heck, look at City the other night. Stones played the conservative role, and Kompany the aggressor. Liverpool - Van Dijk was the aggressor at Saints and Celtic, because of his pace. I'd say he's improved so much because now he plays as the conservative CB, with Gomes often the one using his pace to nip ahead of an attacker. When Lovren's in, he has to be the aggressor because he's a total lunatic.
Now I am absolutely not suggesting Keane is as good as any of the above - he isn't. But it's about balance, just like it is anywhere else on the pitch.
I admit it's a small sample size, but in games v Newcastle and Lincoln, our CB partnership of Zouma and Mina has looked very unbalanced, to say the least. So it leads me to say it has to be Keane and one of them, for now.
