The pen was a nice height for a very good keeper who, having gone the right way, would be disappointed if he hadn't saved it.
He's a decent penalty-taker. I prefer Haaland on them, but Haaland wasn't on the pitch, and in that situation it makes sense for it to be Mahrez, who took most of our penalties last season and did pretty well with them.
Thought he was having a decent game before being subbed after the red card. Took a mediocre penalty and got Rodri's goal disallowed for a handball he couldn't really have avoided, but looked like he was getting his confidence back and was doing okay.
Slow start to this season for him but I'm sure he'll get better.
