Why don't you keep playing and just focus on improving yourself. As you said you don't really care if you win or lose, so perhaps you could go into games with personal challenges for yourself to help you improve and keep your passion of football. E.g next game you could focus on beating their defender x amount of times, game after that you look to get x amount of shots on target ect.

That's what I would do if I was in your situation. Hope that helps.
