I disagree - they might have underestimated them on the basis that they had only one top class player and a collection of others who actually, as it turned out, were pretty good. The big clubs, early on at least would have expected to be able to get decent results. That has nothing to do with the manager, who's clearly very good - its just that fact that man for man it didnt look like their sqaud was comparable - until that is a number of their players turned it on and really excelled.
Liverpool will have to maintain the performances, deal with the expectation (as well as more games) and deal with teams who will come to Anfield and "park the bus" hopeing they can take a point.
That's not disagreeing. Re-read what you quoted.
Liverpool may have been under-estimated on the basis of their squad, not because their manager is a walking parody of himself. Obviously, in the season ahead they won't be under-estimated by anyone, for any reason.
