Inclined to agree. Acerbi seems more likely though.
I was just watching a clip on YouTube of Acerbi; he is very left footed, a decent long passer of the ball (suits our style that), looks pretty solid in the tackle, adept at the interceptions (shows he reads the game) and is happy with the ball at his feet. Some of his marauding runs forward reminded me of our very own Wes Morgan. But I've yet to see anything that shows him under the high ball, or even aerial challenges. Given that we invite crosses, it's kinda vital that he's the kind of central defender that can cope with that. He's more in the mould of Morgan than Huth I'd say.
