I agree with most of this, another good post from you mate.
And because I agree I am also feeling slightly worried, simply because we've bought a player like Alberto instead of the ones mentioned, whom despite being young, have already delivered at highest level. I am worried that it becomes the rule rather than the exception that we are only going for unknown/unsuccessful fringe players at their clubs (or players doing well in smaller clubs like Aspas) instead of picking up the ones that are already highly rated. By that token we would've never gotten the likes of Suarez and Torres for instance.
I know it worked a treat with Coutinho and Sturridge, but instead of only follow this path only he really should've addressed the lack of creativity in the squad. Strategy or no strategy, that seems a great mistake to me especially if Coutinho should get injured. Maybe not as pivotal as the mistake to let Carroll leave without replacing him in the squad - but it's a long Season and we look far to slim for my liking in that area.
