I went with 4-3-2-1 in my first season.
Krul in goal obviously
Santon FB (Auto)
Taylor CD (Stopper)
Yang-Mbwia CD (Cover)
Debuchy FB (Auto)
Tiote BWM (Support)
Cabaye DLP (Defend)
Sissoko BBM (Support)
Ben Arfa AP or AM (Support)
Gouffran or Felipe Guitterez AM (Attack)
Cisse/Remy P (Attack)
I played it in a christmas tree formation with ben arfa and guitterez behind a poached (I sometimes played Gouffran as the poacher)
Fluid - Counter
High line with hassle apponents , run at defence , direct passing.
Subs
Anita
Colo
Elliott
Haidara
The team in general has high work rate and decent pace so base your tactic around those.
I won the league first season with the best defence but didnt score a huge amount of goals. Gouffran was top scorer with 12 !
Cisse , Remy and Cabaye got decent if not great ratings.
Second season Cabaye picked up playing as a BBM and Anita as the DLP. Cisse is hit and miss so you might need a goalscorer.
