They're no where near as bad as most of the UK based commentators let alone the Fox ones. Le Saux didn't think it was a penalty which is his opinion, not sure how it was shameful.
Before the replay, he was saying there was no contact, it was a dive and that Keita should have been booked.
After watching the replay, he meekly says there was contact but Keita made a meal of it and that Naby "threw himself to the ground" and if it wasn't a penalty then Naby should have been booked for diving.
Le Saux does this. He'll make a big claim about a call before he sees the replay and then the replay will show something completely different and then he'll do everything in his power to not admit he could possibly be wrong. I shouldn't be surprised by now. Shameful is a bit strong, but it's ridiculous at best.
