You are fucking blind. Or better yet, you arent blind, you just havent seen Tiago in Chelsea, but still feel like talking for the sake of it (thats way worse). People just dont know how to shut the fuck up when they dont know anything.
Tiago NEVER played behind two strikers. You know what his role is? He is a plain CM who is not that creative or that defensive, but is simply a balance player behind together with a destroyer/DM, his task is to do the simple passes and transport the ball from the defence to the creators and attacking players (those who really know what to do with the ball). That simple, just a balance player who is bit deep, and occasionally box to box when its needed. Thats it. Neither attacking or that defensive, even if as a CM his task is to support the defence more then he attacks.
He NEVER played behind two strikers (the only time this dude has played AM was 1-2 games for us when we had many injuries, and he was bad there, because its not his strenghts despite being a decent passer), the player who benched him was Essien, tell me Essien is an attacking midfielder .
