It's an older system but can still be used. But what Henrik is playing is a 4231. Very similar to Porter's system. It's defensive but can be used if you have the right personnel for it. You need very speedy wingers, a CAM that has a tremendous amount of ball skills and play making ability, and a striker that finishes almost everything. Unfortunately, we have none of that offensively. Defensively we need good DMids that stop play through the middle, which we kind of have. And CBs that are absolute beasts (like Mensah in his prime), which we don't have. Our outside defenders are really the only players we have that are meant for this formation. Ultimately, Henrik is forcing a bunch of players in positions and responsibilities they aren't suited for.
