I finally put my finger on what I don't like about Cesc: his play is narcissistic. He sees the world through Cesc-colored glasses- what clever pass/dink/etc can I make that will be fun for me? Granted, it's not necessarily a bad thing for the team, because he can be quite good at it. But it takes away from the fluidity of the game. When the ball gets to Cesc, there is a second lag time as it enters "Cesc's World- A Magical Place Where Clever Flicks Happen." He sets his sights on something clever, but you get the feeling he doesn't know what else is going on- kind of like a striker's single-mindedness about shooting, he has the same tunnel focus on getting a ball to a player in the box.
It also shows in his petulant attitude towards refs. While Alves comes off cartoonish, Cesc seems more like an angry child who doesn't get everything his way.
