I think this is spot on. While Pablo's experience and attacking quality has got us this far, he's been an exception to the Bielsaball rule as far as player type goes. Klich has worked hard to become that kind of player and has scarcely missed a minute on the pitch as a result.
I've come round to thinking the 'Pablo replacement' concept is a bit of a false mindset because of the exception Bielsa made for his pure attacking quality, which was vital to us at the Championship level, more than compensating for his defensive deficiencies (further lessened by his great work rate and determination). But now I see Pablo's 'replacement' was never going to be another Pablo - it was going to be another Klich.
Cuisance looks like he's going to fit right in.
