The Tiki Taka playing style isn't a bad tactics after all but the main objective of every competing game should be scoring goals. Tiki Taka doesn't give you points it only serves as entertainment to the viewers. What is interesting in the game when you play Tiki Taka through out and lose the game. Many people take their eyes off the main objectives and focus more and pleasing the crowd.
Tiki Taka was introduced by Johan Cruff and perfected by pep at Barcelona it was a great tactical strategy that terorized every opposing team even the great Man United under SAF. But currently modern football has been able to curtail this strategy. With out a regular center Foward it is hard to play that pattern. Moreso such pattern needs a workaholic DM with experience but busquet is old to run that show once more. Xavi needs to work on a new strategy look at even Pep at Manchester City he now has experience players in almost all positions.
