Heerenveen ! I used them on Fifa 12 for ages.
Bas Dost has had a great season for them in real life. Assaidi, Narsingh and Duricic were really good too but in Fifa not sure about real life lol.
I might follow Aston Villa next season for the fun.
Or I'll follow West Ham. Something to get me interested in the EPL other than just watching for entertainment.
I'd also like a team to keep an eye out on in the Serie A, and Napoli or Juve would be my first picks but they are too good now. Palermo might be the one, entertainment there. lol
