What position in soccer should I play?

Play center back or defensive midfielder. These 2 positions suit your best traits but I think you should lean more towards center back.

While both of these positions require the same defensive qualities, the defensive midfielder needs to have some ball skills. The defensive midfielder needs to have good control, passing and defensive prowess to go with that. I would say go with center back, but you can also try out defensive midfielder because it's a lot of fun. If you seem to struggle in which ever position, you could always try the other one.

I'd say either defender (side is up to you) or defensive mid. A team always needs big strong guys for defense to scare away tiny skinny forwards hahaha. You don't really have to dribble much their, just keep the ball as far away from the box as possible and either pass it to your keeper or a midfielder which is where your good passing comes in. Since you're a fast runner I guess a midfield position will suit you if you're looking to run a lot. Instead of using your powerful shots to score you can utilize them to clear the ball up the field. Good headers are again a forward/midfield attribute but I think you can make them work back there.

I think you can be a good footballer if you play in defensive midfielder.

You have no business playing football if you're still calling it "soccer."
