Being better, doesnt means that he is good enough to upgrade our current team in a competitive and looking better in a mediocre club, doesnt means that he will be able to be better with us.
In the past decades, we have seen dozens of players, who seems a bit better than our players, while playing among mediocre players, but once their wear our jersey, they dont seem as shiny as before!
Molinaro was not looking all that worse than Ziegler, before he joined us, neither Melo.
No one can claim that Inler is better than Marchisio, because Marchisio has been proved way much better than Sissoko and Melo, while playing together.
Melo was looking better than Inler does in both club and NT level and yet he is not better than Marchisio.
Ziegler being an upgrade to DC means nothing, if he destined to be our starter.
If he is destined to replace DC, as our sub, it is an upgrade, but if he is not Chie, we downgrade and if he is our number player, it means that we will again be playing with a very limited LB, for yet another season, instead of finding a permanent solution for our most problematic position.
We are we keep postponning the investment on this position, i just dont understand, there cant be more pressing matters, than to upgrade the worst position of our team.
And Lichtsteiner would be indeed be our best fullback since 2006 and one of the wisest transfers ever made since then!
