right, but this is how you learn and make it to pro--you expect this kind of tomfoolery from little league on up through high school, college, to semi-pro. The real pros know all the tricks because they've experienced and suffered from them by the point they reach that level.
In baseball, it's why runners always keep their foot on the base until they watch the 1st/2nd/3rd base dude toss the ball back to the pitcher. It's all fair if you get tagged out on some trickery because you aren't paying attention, as you're expected to learn at some point.
In this clip, I was wondering if that is even legal--seemed offsides to me, no? I guess I don't know the rules once the goalkeeper handles the ball.
