Yeah, long passes are good idea or at least set it by default. Also if you play All attack or More attacking your defenders will be involved often in attack, even your DC can play like FC in some situations and their Opponent Offside levels are too low. If you are sure that your opponent will park the bus it's good idea to give your players more creative freedom. If you play with more disciplined your attacks will be too predictable for opponent's defenders but how successful will be that tactics depends of your midfielder's creativity. It is risked to play with more expressive creative freedom coz your players will do what they want on the pitch no matter how you set your instructions for long shots, crosses, focus passing, etc. and too much luck factor is involved here. Also you will need massed attacks to break through his packaging defensive line. So try Attacking style with shorter or default passes, if result is still equal at half time break change your tactics to more attack or all attack with default/long passes. when you play without wingers is normal to focus passes through middle, at the end of game if result is still negative you can change it to mixed with your full back involved in attacks. Also you can try to beat him with long shots but is preferable to start the match using them rarely. Of course, that depend of your mid players asl levels. About creative freedom if your midfielders creativity is 12+ average try more expressive if not set it by default
