You romantic fools! 46 to 14 in favour of Thiago.
You've all got to remember that Fabregas simply came to be at the wrong time, moving to Arsenal was 100% the correct decision for him and his development. Thiago on the other hand seems to be coming along at almost the exact right time and will no doubt improve as he moves into the senior set-up on a full-time basis. Therefore, forgetting the money issue, it's not fair to simply push the idea of Fabregas returning to us aside when he is good enough (our players, coaches and board agree) and wants the move to happen - He is perhaps the most ideal signing we can make at the moment if you consider all angles.
This said, like someone else pointed out, (the specfic question of this poll isn't phrased the best) no one can replace Xavi and we are likely to have both fabregas and Thiago playing alongside eachother.
