LONDON (AP) — Booed throughout his return to Arsenal, Alexis Sanchez responded to the rancor with a rare goal for Manchester United and reveled in the celebrations.

The forward's fifth goal in 33 appearances since leaving Arsenal a year ago set United on its way to a 3-1 victory on Friday that booked a place in the fifth round of the FA Cup.

With Lingard and Anthony Martial also scoring, Ole Gunnar Solskjaer reeled off a club-record extending eighth successive victory in all competitions at the start of his United reign since replacing the fired Jose Mourinho in December.

With only a short-term contract on loan from Norwegian club Molde until the end of the season, Solskjaer is making it increasingly hard for United to consider any other option for its fourth permanent appointment since Alex Ferguson's retirement in 2013.

Arsenal had a glimmer of hope in the 43rd when Aaron Ramsey weaved in from the left and put the ball through Eric Bailly's legs across to Pierre-Emerick Aubameyang for a tap-in.

It leaves Emery's only route to silverware in his first season since succeeding Arsene Wenger lying in the Europa League which he won three times with Sevilla.
