Xabi Alonso plays 5atb technically...
There is an attacking and a conservative way to approach any formation tbh
i've never seen it not be a somewhat pragmatic approach most of the time, but as you say levkusen use it and have made it work in an attacking sense.
just the last thing we need is not only losing games against our rivals next season, but negative football too. just be a recipe for more toxicity and around we go again.
And yeah before people say anything, yes it would be better than whats happening currently, thats not hard, but once the appeal of a more structured defence wears off eyes and minds will start to crave a team that to takes the fight to teams especially at home
