Dont know where you getting the hanfball from
I thought the foul was given for the collision.
Yes both were entitled to go for the ball and if either got to it late was always going to fiul the other.
In this case it was the keeper.
The only issue was the ref gave a free kick initially.
I think he sensed he got it wrong by the players and crowds reaction
After consulting with the linesman the coorect call was made.
Can see how the Olympic players reacted to it.
At 0-0 they accepted the changed call pretty well because they knew ot was a penalty
