Here is a little difference between us and Mellberg, we are not a professional defenders
ok,
so in this case you do not even have remote knowledge of what a professional defender is able of or not and you just suggest that a professional defender or even chiellini could have done better in that situation ...
judging from some over-powered clumsy looking tackles from last season chiellini with all his power would have pushed a bit to much, gilardino would have fallen (like he likes to) and they would've gotten a penalty ... bravo !
if your opponent is jugling with the ball and you are behind him there is no way of kicking it away ... if you try to step aside and kick it, the ref will give dangerous play and that's it ...
given the position and the distance to the goal i don't see many opportunities for the defender ... so close in front of goal there are many ways a striker could finish
and if you all are honest no one of you would have thought gila would be able to finish this way ... so how could mellberg know ?
