Kevin Friend was like a rabbit in the headlights at Manchester United on Saturday and it was the worst refereeing performance in the Premier League this season, or even for some time.

I will be absolutely gobsmacked if Zlatan Ibrahimovic and Tyrone Mings are not charged retrospectively but you cannot possibly ignore how poorly Friend performed in that game.

Ultimately, the referees are paid to get these big decisions right and to control the proceedings but he was almost sleeping, allowing things to go. When that happens, the authority and respect goes and the players decide to start looking after themselves. That's exactly what happened.
