There has been a herculean difference between how Barcelona is playing now under Quique Setién and how they were doing under the sacked Valverde. And for many that in itself is a huge impact!
It always helps to do a tactical analysis of a game a day later. First, you don't have to break your head on what to write for the day, second, if the game is good you still would be re-entertain yourself with that great performance and most importantly it gets you thinking straight as the dust has already settled.
Even after a day, the happiness of seeing Barcelona going back to their roots hasn't diminished a bit. Like Gab Marcotti said in his ESPN Podcast, it was so great to see Barcelona back.
Hello Barcelona, Glad to See You Again!
