Firstly, you talk as if you think we will stop all spending and reinforcing with the purchase of Kun. Not sure what makes you think we will not continue to fix the defense?
Secondly, the lack of WC fullbacks is certainly a problem, teams will rip us off to get them away. Not to mention, these so called WC fullbacks all play for clubs that pretty much have a shot at winning trophies all season long, we can't offer that.
Thirdly, if you are seriously OK with Quag, Matri, Toni, and Ale there is no way in hell that will get us a top 3 finish...NO WAY man, so having WC fullbacks will certainly help us concede less but they will not guarantee clean sheets anymore than they would guarantee 3rd place.
Fourthly, while teams like Milan/Inter/Roma/Napoli continue to upgrade their teams with CL money, we will essentially making our selves less lethal. Sure, we would have a sturdy backline and that's all fine and dandy but how is a nice defense going to help us unluck the opposition and create chances? It's already been proven that you shut Krasic down you shut our offense down. The quartet you mentioned can't do it IMO (again, its just my opinion, certainly I'm not saying it as factual as it might come across)
Fifthly, remember when we signed DP a long time ago? Look at how long he has been giving this club wins after wins, goals after goals, assists after assists. We have the opportunity (distant yes I know), to bring a player that can do that for the next 10 years or more...someone to redefine this club just as Ale did. Next year we won't have that opportunity and we will be left with a very limp attack...maybe bring a WC striker next year but no one to work off with. Trez wouldn't have been who he was without that legendary partnership with Ale. We need that for an attack, just as we need good full backs. Both are important equally(again, just my IMO and how I think tactically)
Sixthly, Possession. I know you all hear me say that and wonder how that related to conceding. Well, I just have a gut feeling I guess that if we were able to control the flow of the game, we control the chances against our goal as well. If we can't keep the ball and our defense always plays long balls, then we will continue to see endless counter attacks, etc. Fix the midfield, get us a WC threat up top, and new full backs and you will have a fantastic team. But, just as the FB situation can't be ignored, either can buying a player like Sanchez or Kun.
Lastly, Kun would be the best option for us but if we have to pass for whatever reason then I'd be happy with Alexis though I feel Kun would bring us up so many more levels. Regardless of the player, one of them should be brought as a replacement for Ale. Our fans know it's Ale's last seaosn, well full season anyways and this club deserves to have a player that can create that spark and connection that Ale has done for so many years.
