Yes, they all played an important part in the goal. It was a very good team move. But what I meant was that it was Vidal's contribution that really made Lazio struggle, as that pass gave us a lot of time. It completely put Lazio on the backfoot, and we were ahead by several seconds, even finding ourselves in a 2 against 1 situation that we was then able to execute easily.

Looking at it again, it's just a damn fine team move. Vidal plays his part, and should be praised for it, but I see it now that Licht and Chiellini are equally important in placing us in such an advantageous position to score. I agree with you @Qwisto
