Manchester United sent an ominous warning to the rest of Europe with an emphatic victory over CSKA Moscow in the Russian capital.
Jose Mourinho’s side maintained their winning start to Group A and kept on course for early qualification for the knockout stage with their brutal demolition of CSKA.
Romelu Lukaku scored twice, with Anthony Martial converting a penalty, as United went in 3-0 up at half-time, before Henrikh Mkhitaryan added a fourth after the break.
Substitute Konstantin Kuchaev added a late consolation for the hosts.
United may have been missing Paul Pogba, Marouane Fellaini, Michael Carrick, Phil Jones and Antonio Valencia, but Mourinho’s side made light work of their hapless opponents.
