Romelu Lukaku showed just why Manchester United splashed the cash to sign him as Jose Mourinho’s men earned early bragging rights against bitter rivals Manchester City, courtesy of a 2-0 win at the International Champions Cup.

Belgium international Lukaku, who arrived from Everton for a reported £75-million, opened his account in the 2-1 friendly win over Real Salt Lake on Monday.

And Lukaku made it two goals in two games, with Thursday’s opening strike in the first Manchester derby played on foreign soil at NRG Stadium in Houston, Texas, where Ederson and Kyle Walker made their debuts for City.
