Would you say that LvG inherited a title-winning squad because he took over from Moyes just a season after we won the title? I wouldn't. The squad needed huge upgrades - just like ours even after finishing second. Hark back to that summer and everyone was talking about Liverpool being challengers to City...not us. This was because you could see where each team was headed. We do have hindsight now, so let's see:
1. Matic was already done by the second half of the season - it was showing, but he was one of Jose's favourites and "undroppable"
2. Valencia was done too - but somehow Jose continued playing him game in, game out
3. Young was ageing, Mata was done too, of course. Zlatan was gone. Lukaku, we know by now, wanted to be out at the earliest too (his words, from all his recent interviews)
Effectively, DdG was all that stood between us and repeated rammings from the opposition. We lacked creativity from wide areas and Jose had stunted the development of Martial as well as Rashford with his bizarre preference for Lukaku and Alexis...with even Fellaini preferred as an option in attack over these.
So no, that "squad" was not the second best. We desperately needed midfielders, full-backs, a RW / RF, a 10 and a CB. We now have FBs covered and the CB too - but clearly still need the 10, RW/RF (James should be backup and Ole mentions this even in his recent podcast) and another midfielder.
In addition, we needed to clear the immense quantity of overpaid underperformers - some of who still remain with us. To me, this situation qualifies for "train wreck" as a descriptor.
