[LittleDalglish]

Currently managing Blackburn Rovers in my second season on this save. After 13 games my side lie top of the league, having beating Man United 3-2, City 3-1 and Chelsea 5-1. However need help on my midfield selection-
Current 4=
Sigurdsson Nzonzi Jenas Drenthe as a flat 4 in midfield but i also have-
Hoilett
Hamit Altintop
Pederson
Mahamadou Diarra
Petrovic
Seedorf
Which players should i pick or if the 4 i play at the moment the best i can choose? Any transfer help would be useful aswell, my current team is-
Robinson
Boswinga-Marko Basa- Dann- Olsson
Sigurdsson-Nzonzi-Jenas-Drenthe
Rochina-Sow
Thanks

I prefer Diarra over Jenas but if they're working for you don't change them after all you're top of the league.
