Compare Valverde team to current team before you compare their seasons. At least Valverde had a striker and a transfer budget.
Eh, let's compare:
Messi 18/19 is better than current Messi but current Messi is among or even the best player in the world. So either EV or Koeman has the world best player in their squad.
Braithwaite is not comparable to Suarez but Griezmann is not bad this season, plus higher workrate.
Alba this season is as good as Alba pre Anfield.
De Jong is top midfielder right now, better than Rakitic or Vidal or Arthur.
Pedri, same with De Jong, is considered by many here as better than Rakitic, Vidal or Arthur.
Busquest is Busquest.
Dest, some rates him higher than Roberto or Semedo.
Dembele, fit more than ever.
Stegen is not as good as himself under EV.
Same with Pique and Lenglet but then Minguenza and Araujo are fresh air.
Puig, top 5 midfielder in the world.
So overall, look at quality of players, at least base on this forum metric, it seems most of current players are better than EV's players.
