That’s just ridiculous lol. While I think a change is needed after that result, to say Tata is better than valverde is quite crazy.
Tata had younger messi, Alves at rb, Neymar, iniesta still in his prime, Busquets still in his prime, and ended trophyless. He also moved away from Barca’s style, just less effectively, so people can’t be hypocritical in the style issue. Also, when lucho and valverde moved away from Barca’s style, it was pragmatic, Barca didn’t have the players to pull off the style because some players were old and slow, guys like rakitic can’t play in a tiki taka system, etc. When Tata moved from the style Barca still had the players to execute it (younger Busquets/Pique, had iniesta in his prime, Alves in his prime, Xavi was still around albeit older)
Valverde has flopped in Europe but you can not deny the work he has done domestically. Barca are consistent in the league with a strong defence.
