TheSteezyKoalaCosta definitely is stronger than Lewa in my opinion, but Lewandowski is a better striker and not a cunt. Costa is cunty enough to deal with the EPL defenders like he dealt with Ramos and Pepe when playing Real. I think he will have a great season. Chelsea, at least on paper, look like favorites for the title.
I would take Lewandowski over Costa any day, especially after his WC performance. Lewandowski has a nose for goal that is hard to find, and playing on a team like Bayern, he could challenge for the Golden Boot.
He may able to handle Ramos and Pepe for minimum 2 games a season, but I don't know if he can handle defenders like Kompany and co., Vertonghen and co., and Koscielny and co., minimum 6 times. The caliber of defending in the EPL is much higher than that of La Liga. Outside of AM, RM, and Barca, the defending is mediocre at best, and to be frank, RM, and Barcelona looked very shaky in the back many of their games. Will he be better than Torres? It will be hard not to be, but I don't think he will be the new Drogba.
I think Man City are still favorites, and by quite a bit. They needed to merely upgrade their CB which they did, and they even added a new CDM.
On a transfer note,

I am kind of bummed Liverpool or Man U did not take a run at him.
