This whole 'Amavi wanted it' bit is also irrelevant to the question of whether it was the right or wrong option.
Not it isn't. At all.
Yes it is. Do you pass the ball to just anyone, in any position, just because they shout, or do you look to see if there are say, opposition players nearby?
No it's not. You are posting a bad angled photo that shows less room than there really is. It also fails to show how wide open the 3 Villa players are in the middle. Here is an actual photo of when Amavi received the ball. Notice the 3 wide open players to his right that he could have easily passed to, but decided to dribble. How in the world this is Guzan's fault with evidence like this is beyond me.
Well, yours is a fraction of a second before mine as well - he hasn't shaped onto his right foot yet, but whatever - but I don't need to quibble about camera angles. What happened is what happened, and we know the end result. Guzan rolled the ball out, Amavi made a poor touch and a bad decision, and the player who was bearing down on him robbed the ball off him. I've already said it's Amavi's fault that he chose to dribble, and that he made the wrong choice - I said so in the passage you've quoted above. Nothing's going to alter the fact that Dann was bearing down on him quickly and that, in this case, rolling the ball out was the wrong thing to do.
I believe the facts clearly indicate the presence of a second shooter on the grassy knoll.
