First of all I want to reiterate that Roma played a mighty fine game in that second leg in the Stadio Olimpico, but Barça's main issue was attitude, something players hate being accused of but if we ever had a proof of this particular issue that gets thrown at teams from time to time, the capture of Iniesta spurring the players before coming out to play the second half will become infamous... A man of Iniesta's experience knows these things and he obviously didn't like what he saw in that first half which at that moment was only at 1-0 with a lot for Roma to do. Still, his words were that, more of that and Barça are going home in the tournament.
That more refined attacking options may have been beneficial, I won't deny that because you can never have enough magic up front. But the players that took to the field for Barcelona on a 1-4 advantage should've had it easy that night by being intelligent, but not easy in terms of being permitted to be lethargic and arrogant.
Neymar has tremendous qualities but he also has many flaws. His flaws for me outdo the beneficial attributes he offers and I don't like that type of player. All that without going into the manner he departed from Barcelona which is a different debate that has already been exhausted here at TF365.
A team that plays in the manner Barcelona traditionally plays in is much more balanced by having that extra man in midfield, one wit the necessary talents to play in that midfield mind you, which isn't easy to find. Hopefully Arthur is that man, he definitely looks to be. Yes, it's a lot more spectacular to play a tremendous trio up front, we've been witness to that for four years at Barcelona, but hell, you're not going to tell me that the 4-3-3 formation didn't leave the team so open in midfield and subsequently in defence that many games before the front three managed to kill the game weren't games that also had you living on the edge with the amount of chances they let the opposition have. Many games that ended in the correct side of the score where Barça were concerned could've gone the other way. I personally feel more secure watching them like this to be honest.
