Pretty much everyone for Barca had a mediocre match against Inter and the best manager in the world. You think if Nasri would have played in those matches that Barca would have fared better? Of course not.
The rest of your post is meaningless.
In barcelona, last 20 mins, they were pouring at inter's goal.
Inter was getting very tired from running down every bit of space, winning duels, with one man down, barcelona didnt had an answer, iniesta was crap.
then, they pulled pique and busquets in the frontline, making a total change in gameplan.
however, they had no one really connecting, and were lucky to score once.
Nasri plays such games often in the epl, partially because arsenal isnt nearly as good as barcelona, who win 99% of their games because their attack is exponentially better then opponent attack and defence.
When they'd put pique and busquets up front, and subbed iniesta out, and nasri in...
the summer that came afterwards predicted the future downfall of barcelona, instread of seeing the problem that when their attack is nullyfied in a game, and they'd need to powerplay and break the opposing defence, they have no options.
instead of fixing that, they bought villa and let zlatan go. they got another talented 1m70ish player.
