Saying worst was probably too harsh, edited it out now.
While Alexis would have been better than Pedro, I don't think Cesc would have done better.
It's not like Rakitic is not creative at all, he just can't break the shackles when he has to cover up for a player who is doing nothing but delivering useless crosses most of the time.
Saying Cesc sucked in the 2nd part of every season and that he failed at Barca has become like a tradition here. The reality is a bit different. He wasn't what we needed because we had Xavi. Xavi was the playmaker of this team, so Cesc, naturally, was played in all sorts of exccentric positions, like on the wing or even as a false 9. But now, now we don't have Xavi (sort of), and Iniesta is declining fast and not becoming any younger himself. A double pivot, Busi - Mascherano and Cesc in front of them as a 10, with Messi back as a forward, with Neymar - Suarez on the wings woud've been the best thing for this team.
I see it now. My guess is that Lucho didn't want Cesc because he plans to use the midfielders as cover for the very advanced fullbacks, relying on Messi to make the difference centrally. The thing is Messi doesn't have the required workrate to make it work. Xavi ran 11-12 km. every game, always top 5 in his team. Messi can't even come close to that. Off the ball movement was one of Xavi's fortes. With Messi, it's probably his weak spot.
That would have been great:
