Manchester United and Manchester City are no strangers to feisty derby clashes. There have been several of them in recent years. While derbies in England have undoubtedly changed in recent years, in comparison to how they were played in previous decades, they are still always played on the edge. There is always the chance of them spilling over - either on or off the pitch.
The domestic success of the Blues since the takeover in 2008 has added a different element to the Manchester derby. It used to be United who came into the clash as favourites, but now, more often than not, it is City who are expected to win, regardless of the competition or venue.
It is still the Reds who boast the better record in the derby, but City are gradually catching them up. When the two sides met back in December 2017, it was, in many ways, a throwback encounter. It was an entertaining clash on the pitch, but it was off the events off the field, specifically in the tunnel, that dominated the headlines.
