Lack of keyboard and mouse controls in online mode

I'm curious about the lack of this feature, as I'm single-handed. It would even out the game for people like me against regular players. A particular example is player movement and shots on goal. Movement allows for only eight directions, which change dramatically, making players lose their dynamics, and shots require luck and goalkeeper error. That's why I'm asking why there's no keyboard and mouse control in online mode, despite this feature being in the game.
