Jadon Sancho and Cristiano Ronaldo gave timely reminders of their value with both on target as Manchester United got their Europa League campaign back on track with a 2-0 victory at Moldovan side Sheriff Tiraspol on Thursday.
Dutch club Feyenoord also registered their first points in emphatic fashion, crushing Sturm Graz 6-0 in Group F where Lazio were hammered 5-1 away to Danish side Midtjylland.
Jose Mourinho's AS Roma scored three times in the second half to beat 10-man HJK Helsinki 3-0 in Group C -- Andrea Belotti scoring his first Roma goal to seal the win.

Sheriff, who downed Real Madrid in the Bernabeu in last season's Champions League, offered an occasional threat but three-time European champions United were unruffled on their first ever trip to Moldova.

Iranian forward Alireza Jahanbakhsh scored twice in Feyenoord's romp against Sturm Graz to move top of their group on goal difference with each club having three points.

It could have been even worse for the Italians with Midtjylland also missing a penalty.

French club Rennes were denied their 100% record in Group B after Turkish club Fenerbahce struck deep in stoppage time for a 2-2 draw having trailed 2-0.
