It depends on what do you find enjoyable. Yes, you can play and have fun. But no, you can't be a successful manager: for that you need to watch videos or pay money.

I guess you don't want to do individual trainings too, because they require micro-management, thinking and planning. So just keep bonuses on 10% and do obligatory trainings between games, they have a huge impact on performance. That may be enough to win League, but CL and especially Cup will be tough. Asso tournaments depend on the tier, don't expect to play in higher divisions.
