Curve

I think I know what you are trying to say, but that's not a good sentence. I think you mean to say "The ball curved into the goal." (keep -> goal??)

Right or left?

Right ?

Ok ....yes i think u got what i was trying to see, and ur answer is perfect , so "curve " can be used to indicate like this ...." a special way of kicking a ball that makes the path curvedly" haha ... quite complicated explanation .isnt it ?

The technique is also called "bend."

:)thx for ur help
