I don't know why you keep using the word intentional, each goal there the player shot the ball expecting the ball to go into the goal. Like I said its not like he shanked a cross and it goes into the goal, which is pretty common actually.
I mean obviously a goal from that far out has some "luck" to it, and by luck i mean that player is only going to be able to make that shot a handful of times. But that is what makes it great when they do make it happen in an actual game, hence why it was the #1 goal. I mean you could apply this argument of luck to like a shit load of game winning shots in basketball, but I mean that shouldn't take away from it being an amazing shot/goal...
And trust me I know where your coming from, when someone purposefully has a play in there mind and it works out perfectly aka henry goal, it def adds a lot of value to the shot. But just because a goal doesn't have that calculating aspect to it, it shouldn't discredit it.
