yea cesc at this point does not seem suited to this barca team
as for iniesta/ fabregas thing let me put it to you this way...what iniesta does(dribble,pass quickly,movement,versatility) that cesc cant do only a few/handful of players besides iniesta can do do...meanwhile what cesc does that iniesta cant there is many players that can do what fabregas does (score goals from midfield/direct attacking)..thats the difference between them and thats why iniesta is a better player and much more harder to replace than say iniesta
Just my opinion, but if ask which player I want, I will pick Cesc, just because he brings more impact. As great as Iniesta is(never denied this), he will only truly shine in that system, and with the right players around him.
My thing with Cesc, i've seen him run a team, being the main man through the middle. I haven't seen Iniesta do that, he's a great player, he's never demonstrated he can be that main man in the middle.
