First of all, the biggest issue we had with Tata was not tactics but motivation and fitness and it showed towards the end of the season when we could barely create any chances against the likes of Getafe. That's also why writing something like Tito=Tata=Lucho makes no sense whatsoever. Also about Tata, it was really painful to watch Barça playing last season, and not only towards the end. Our playing style was awful with him and my eyes clearly prefer Lucho's approach, regardless of the results.
Second, we were very messidependent even with Guardiola, even then almost any attack went through him, the difference being that maybe Messi was better back then. The best testament to that is the fact that Leo scored 50 goals 2 seasons ago.
Third. Guardiola's tactical mastermind is often overstated on here. He had a clear vision, a great idea, the guts to make unpopular decisions, great motivational skills and the best players at the right time. But he has to date not become a tactical mastermind in the sense that he struggles to operate outside his football philosophy and to adapt to opposing teams or different circumstances. The only "tactical variation" we've ever seen of Pep was playing a double pivot in CL away games, that's it. He doesn't vary his tactical approach at all, he just tries to impose his system on the opponent. If it works, we see some of the best football ever played, and if it doesn't, he loses 0-4 to RM. Which brings me to my next point:
4. Tactical variation. This was the first game of the season that was really tough, and we didn't do well, but it had more to do with stupid individual errors than with any tactics. We lost the ball all the time and subsequently didn't nearly have as much possession as in other games. I don't think it was Lucho's game plan to lose the ball or get dribbled all the time. Either way it is far too early in the season to talk about tactical variation or Lucho being stubborn. Let's do this when we play like this for several games in a row or can only score 2 goals in 6 matches against Atlético like with Tata. Lucho proved last season that he is very capable of varying his tactics.
