Alexis Sanchez arrived at Old Trafford from Arsenal in a swap deal involving
Henrikh Mkhitaryan
After an uneventful first half, Romelu Lukaku gave United the lead on 55
minutes with a close-range volley.
Sanchez was then fouled by Huddersfield defender Michael Hefele to win a
penalty and the Chilean, a January signing from Arsenal, stepped up to
take the spot-kick.
The forward saw his low shot saved by Jonas Lossl, but made no mistake
with the rebound to double United's lead on his home debut.
It was an emotional day at Old Trafford as United commemorated the 60th
anniversary of the Munich air disaster with a minute's silence before kick-off.
With Premier League leaders Manchester City drawing with Burnley in the early
kick-off, second-placed United narrowed the gap to 13 points.
But it was a fifth successive league defeat for Huddersfield, who are without
a win in eight league games and now sit 19th.
Pogba dropped, but Sanchez makes his mark
Jose Mourinho rung the changes after the 2-0 midweek defeat by Tottenham
and the United team sheet raised a few eyebrows before kick-off.
Centre-back Phil Jones, who scored an own goal at Wembley, was dropped
from the matchday squad all together, while 21-year-old midfielder Scott
McTominay was preferred to £89m Frenchman Paul Pogba, who dropped to the
bench for the first time since his return to the club in August 2016.
United felt they should have had a penalty after 20 minutes, when Terence
Kongolo clattered McTominay in the area, but referee Stuart Attwell waved
away their appeals and the youngster continued after receiving treatment.
Despite enjoying more than 76% possession, the home side lacked fluidity and
creativity in the first half and failed to trouble Lossl, bar a long-range
effort from Sanchez and an early attempt from Jesse Lingard.
Sanchez, making his third start for his new club, appeared to be getting
more frustrated as the half wore on and he was booked for a petulant foul
on Florent Hadergjonaj.
United started the second half with real purpose and deservedly took the
lead when Juan Mata's cross was met by Lukaku for the Belgian's 19th goal
since joining the club.
With 25 minutes to go, Pogba eventually came on and United soon had their
second before the game petered out.
In addition to the three points which keep United above Chelsea and
Liverpool in the race for second place, Mourinho will be happy with a 15th
clean sheet in the league this season for David de Gea.
