He missed the shirt pull on Socratis, but not easy to see real time and that is where VAR should be helping. The Saka incident was absolute clear simulation, he intentionally moved his right leg out to initiate the contact and then flung himself down. Outstanding decision by Mike Dean, and remember he only got to see that once from one angle and immediately signalled it.
I thought it was an outstanding performance, and for me he is still as good as any referee we have in England. Obviously not as young and mobile as the likes of Oliver, Taylor and Pawson, but his decision making and control of the game is up there with all of them.
