Before Pizzagate and Roy Keane’s tunnel clash with Patrick Vieira, the spiky rivalry between Manchester United and Arsenal was created by a mass brawl at Old Trafford in 1990 that prompted the first and only ever points deduction for players’ bad behaviour.
Former United captain Steve Bruce was among the 21 players involved in the stormy aftermath after Nigel Winterburn had flattened Denis Irwin with a retribution challenge.
And though Bruce doesn’t condone some of the behaviour, he feels the modern game would welcome a bit more emotion on the pitch and along the touchline – as we saw when Thomas Tuchel and Antonio Conte clashed in the recent Chelsea-Spurs derby.
