Advice needed for playing away game
I take charge of Leverkusen and usually play default 442 formation.
Once my team is in away from home,I give less harsh team talk as possible and use the same formation as home game.
Unfortunately,i virtually lost all my away game even opponent teams inferior to my team.It makes me so frustrated!!
Here comes with some questions about away game.
1)I would like to know if there are some crucial settings for away game that I miss.
2)how to defend a lead when in away game.
3)What should the mentality of two forwards and wingers be?(give me some idea,thx)
4)Is it necessary to set my back 4 to ultra defensive with nobody setting "forward run","run with ball","try through ball"....?
5)What's the basic setting of team instruction when in away game?
6)Should let my two central midfielders holding up ball to keep possession?

Hoping there are somebody can answer all or some of that to solve my problem(always lost in away game),I will be appreciated so much.
