Manchester United manager José Mourinho has suggested his side's lack of intensity contributed to their 3-1 defeat to West Ham United at the London Stadium.
The defeat was their fourth in all competitions this season and equalled their worst ever start to a top-flight campaign in 29 years, having accumulated just seven points from ten matches.
The loss also condemned the Red Devils to a third consecutive match without victory, with the Portuguese insisting that his side didn't get off to the best of starts, following a draw against Wolves in the league and a penalty shootout defeat at home to Derby in the Carabao Cup.
