I wish his transfers since the treble would have been such hits as in earlier periods. the signings of Bernardo, Sterling, Mahrez, Dias, Ake, Rodri all turned out great and allowed us to build on them for years with high performance from them regularly. and the likes of KDB of course from a bit earlier period.
since the treble not sure how many of those we will be able to see 4/5 years of great seasons from each player. Gvardiol is one that looks like one similar to above mentioned, the rest has still time to prove themselves but not too much.
not only Txikis fault, the whole club became comfortable after the treble win business wise, and what happened is while we were significantly ahead of likes of Liverpool, Arsenal at that point we allowed them to catch up by better transfers also by us regressing tactically/became easier to play against.
there was some tendecy to get runners, players with good press resistance, players that can beat opponent 1v1, but somehow this did not follow up tactical changes and we still tried to play like at our best with possession based/control type football where you need high level technicians in possession rather than good and quick dribblers.
now with Leijnders coming in there might be more to this tactical change, we will see this quite soon imo August, September how this is planned exactly but certainly there was a bit of a mismatch of the recuritment ad tactical shape/idea since the treble which is so strange from such a close knit DoF/manager duo as Txiki and Pep.
dont get me started on last summer, which is still so hard to understand how let it happen, when apparently DoF/analysts all flagged a big rebuild must be done, but Pep wanted to have one more go with the old guard which backfired big time.
Palmer has to be mentioned too, not down to Txiki imo, more like Pep, that he is what Salah/KDB was to Chelsea, they had them and didnt think they re worth to keep/develop and reap the rewards after. still its not gonna be nice to see Palmer scoring/assisting almost every round, its just fucked up I bet Chelsea fans looking at Salah end product for years, or KDB's brutal legacy at City was hard to swallow too...
on the positive side, Txiki was a great DoF overall (expect last 2 years), the transition from where we were early 2010s to more than a decade later was partly down to his work.
currently good example what a mess going on at Newcastle who had their DoF stolen (Ashworth) then hired Mitchel who resigned leaving all kind of vacuum at the top and now Newcastle instead of building on their recent success looks about to implode somewhat.
