are you talking about your midfield? I have noticed that my MC's (also MR and ML) performing really really bad this season. They usually getting 4-6 rating - I'm playing 3-1-2-3w, narrow diamond or V-style usually. I even replaced my MR with another one - but nothing . I heard that sometimes they perform better if you put them on other position yeah but what to do with MC ..I think its all about luck. Next season I will focus on checking players ratings before I buy, only problem is you cant see at very first day -.- oh and some say you should keep those 18/19yo players because there is always chance that they'll perform better next season.
