The presence of Xavi as Barcelona coach to continue the tiki-taka style,
Each coach has many variations on each tactic used, so it can't be considered taki-taki an outdated tactic.
When Xavi was still active as a Barcelona player, he became the brains of the tiki-taka game and could set the rhythm of the game and the chances he created turned into goals.
This trend is being carried out by Xavi to bring Barcelona back to the spirit of the game. when the tiki-taka strategy can blend in with all players, it will be very difficult to stop the flow of incoming balls. 6 trophies in one season is proof of how dangerous tiki-taka tactics are.
It was a fantastic past for Barcelona and I will always remember the glory they had, but now it looks like it will be difficult to repeat it. And in the end all doubts were answered in last night's Champions League group stage decider for the Barcelona squad. This is of course very unfortunate because this is not a common thing for Barcelona, but given the team's condition and finances are very bad then I only consider it as a consequence they have to accept.
