Iniesta is great, don´t get me wrong. IMO he does NOT belong on a 5 man shortlist for world player of the year though, and never has. Playing for Barcelona and Spain I think he scores and assists too little in relation to where he plays on the pitch to warrant that.
We all know football isn´t just about goals and assists, but you can´t completely disregard it since they are ultimately what matter. I only added Walcott as a comparison since he is all about stats really. If he doesn´t score or assist he is usually pretty poor.
This and last season, all comps:
Walcott - 20 goals, 23 assists, 74 games
Iniesta - 18 goals, 21 assists, 101 games
No one would dream of branding Walcott as one of the top 10 or even top 20 players in the world in the last 2 seasons, and yet he outperforms Iniesta in both goals and assists. He does so playing only 3/4 of the games Iniesta does as well!
Iniesta is great, but IMO he is also held in a bit too high regard world wide in relation to his actual output.
