The cancelo one was as simple as they come, he's not created that, cancelo's run has created that, I'd expect every single player on the pitch to play that ball. I've yet to see any highlights and honestly don't have any recollection of the mahrez one.
As for saying 2 assists tonight turns him into a £100 million player, maybe for the media and the social media lot who just look at the score and see the 2 minute highlights but I'm basing my view on his overall game and contribution to the side over the course of the game and its currently nowhere near enough.
