For me,it's all about possessing a good,solid defence with a reliable goalkeeper that can put on a world-class performance when needed,as well as a strong holding midfielder and then a box-to-box who generally goes forward and comes back when needed.It's all about all-round play for me.
A solid defence,tight midfield and possibly just a tall,strong lone striker.I tend to play the 4-1-4-1 but my favourite formation would be the 4-3-3 with wingers.Having three different kinds of midfielders gives it that sort of balance for me and I usually like playing it with Manchester United or Arsenal,or even in my current save/story,Standard de Liege in Belgium.
Not the best at transfers though,I never really find a play that suits,what could be said,my high standards.I can find the right attributes to fit the player but never the player that fits the attributes themselves and sometimes end up buying nobody in order to strengthen my squad.
I would call myself a defensive manager,rather than attacking,but I am knowledgable in how to attack effectively.
