It looked really fucking simple, but Mahrez is so good at disguising his intentions and especially his shot. The last defender had no idea Mahrez was about to shoot and didn't even stick his leg out, and the keeper couldn't even get down to the first post.
The last 52 PL games Villa have conceded first they have lost 46 of them and only won one. Not seen anything at all from Villa so far to suggest it will be another defeat and quite probably a resounding one
