Alberto Moreno isn't worth £16m

Sure, he's 21, but will he develop into the all-round left back we need? Let's compare him to Jon Flanagan and Jose Enrique over the last two seasons.

*Note: Jon Flanagan's '1st season' are his stats from league appearances from 2010-12.*

At a glance, Moreno is not much of an upgrade from Flanagan and no where near as good as a healthy Enrique.  All he really brings to the table is a better interception and blocked shot rate, which is admirable, but not worth £16m.

Enrique does turnover the ball significantly more than the other two, but his back pass rate tells me that it is probably primarily in the opposition third and his chances created per 90 somewhat makes up for his risk-taking.

We definitely need more coverage at left back, but I don't think Alberto Moreno is the answer.  He would probably be a solid addition to the squad, but if you are going to spend £16m, you should be buying a Sakho and not an Aspas.
