Need to see it a few more times there may have been contact but only slight. As you say swan dives never look good. Ps Amad not at the races in midfield.
It' a penalty, but from the refs angle, he's unsure and Roberts' theatrics go against him. If he'd just fallen down, he might have got it.
Can completely see why the ref thought that was a dive. If he’d been the pother side he have seen it.
