I'd take Ake over Maguire all day long. if indeed there is any truth whatsoever in our reported interest. In him, or a any new defender at all.
As defenders, there isnt much separating the two imho. One is taller. The other is faster. that's about it? Both are home grown.
However as a hollistic decision, surely Ake makes much more sense, he is younger, much cheaper, and thus has plenty of re-sale value and long term prospect. Sure, sometimes you pay top prices for proven top players knowing fine well you'll never recoup any of it, and that is fine. is Maguire really that type of player? not for me (i'd obviously welcome him if the club do sign him, but not exactly jumping for joy at the thought). Ake i wouldn't say is (yet) that either, but he would provide cover and options at a reasonable cost with plenty potential further ahead too. its not a short term fix move.
and if we don't bring anyone in at all, i'll be fine with thst too. imho, we will miss VK more as a personality than a defender, given how little he has been available in the last couple of seasons, and indeed how little he played. imho the last stretch of regular starts was more of a send-off (pep took a similar risk with abidal at barca as a personal gesture) than a footballing decision. worked great as both either way.
