This Wenger charge for calling into question the integrity of the referees

[Burney]

So I have seen some ex refs say no pen on Wednesday, and others say Pen... so what happens when we get Video ref and the onfield ref says pen, and views it again and still says pen, and the video ref says no pen?

My guess is that the video ref will be allowed to make recommendations to the on-field ref and give him the opportunity to change his decision. That's how I'd do it at first anyway.
