What I would ask mate is whether replacing Cazorla/Podolski/Theo with a Di Maria/Reus/Navas would make us stronger than replacing Giroud with a top class / world class forward, ala Suarez/Higuain/Benzema?
Di Maria might be available, it's well known he is not happy warming the bench at Real Madrid. No way we will get Reus in mid season, he will probably be going to Barcelona anyway.
