At the present, I don't rate Alexis lower than Aguero, Hazard and James Rodriguez, and based on numbers and performances, I don't see any reason why I should. You have Messi, Ronaldo, Neymar and Suarez who are clearly the best (in form Robben gets the 5th spot, but he was injured when it counted most) . After that, there are several players that are close (Aguero, Hazard, Sanchez, James Rodriguez). In one week Aguero has an amazing performance, the next week Hazard seems like he has the edge, and other times it's Sanchez or Rodriguez who look the most in form out of the 4. And yes, I think the attacking players are the most valuable at the present. The top midfielders have declined (Iniesta, Xavi - almost retired, Schweinsteiger, Alonso), have been injured for the most part of the season (Modric, Thiago), are still developing (Pogba, Verratti, Isco, even Rakitic), and the defenders are not at all at a great level (besides Pique and Thiago Silva, who are clearly the best, maybe Ramos and Boateng too, but not this season). Goalkeepers should be rated in a separate section IMO.
