MANCHESTER, England — The fourth goal, the one that signaled a victory turning into a rout, was the one that meant the most. Manchester United’s coaching staff poured from the bench. On the sideline, several of the handful of stewards standing guard over Old Trafford’s empty stands celebrated wildly. And on the field, the players grinned and roared and beamed from ear to ear.
Most of them, of course, would be too young to remember the last time Manchester United met Leeds United in the Premier League. Scott McTominay, scorer of two goals inside the first three minutes on Sunday, for example, was 8 then.
