Manchester United cruised to a 4-0 win on their return to the Champions League for the first time in three seasons as Azerbaijani champions Sabah were taught a lesson on their debut among Europe’s elite on Thursday.

Matheus Cunha, Bruno Fernandes, Benjamin Sesko and Lisandro Martinez were on target at Old Trafford as the Red Devils took advantage of a kind draw to get their Champions League campaign up and running.

United have made an uninspiring start to the Premier League, picking up just four points from their opening three games against newly-promoted Hull and Ipswich and a trip to Everton.

Yet the difference in class between the three-time European champions and a club only formed nine years ago told once Cunha opened the floodgates on 27 minutes.

Sabah navigated four rounds of qualifying to earn their night at the Theatre of Dreams.
