Herrera’s pass was perfect and Mkhitaryan took it on before unleashing a fierce shot that flew past Lloris.advertisementIn his last four games, Mkhitaryan has scored two goals and set up two others. His injury may set him back once again, however.Meanwhile, the Premier League has now seen players from 96 different nationalities score goals since its inception in 1992.It was a big win for United and Mourinho, whose record against the so-called heavyweights of the Premier League has been poor since arriving at Old Trafford.United had the better of the chances in both halves, with Paul Pogba particularly lively in crashing a free kick against the crossbar and having two shots well saved by Lloris.Christian Eriksen was Tottenham’s best player and from one of his free kicks, an unmarked Victor Wanyama misdirected a header from the edge of the six-yard box in the 55th.Spurs didn’t have a more clear-cut opening for the rest of the match.
