You lost because your GK played horribly.

You don't have to change your formation, I would say use a 4-1-4-1 but you don't have a ML.

The only think that I could suggest is to set your orders like this:
- Mentality: Normal
- Passing: Through the Middle, Long
- Tackling: Normal
- Pressing: Whole Pitch
- Marking: Zonal
- Counter-Attacks On
- Offside Trap Off
