Jose Mourinho says Manchester United striker Anthony Martial is happy again and working harder now that he is back on the goalscoring trail.

The France international scored twice in Wednesday's 4-1 EFL Cup victory over West ham – the same number he had managed in his previous 13 appearances across all competitions this season.

Mourinho feels Martial's work-rate has improved, acknowledging the forward was unhappy after his slow start to the campaign.

"He is working harder than before, to be honest," Mourinho said ahead of Sunday's Premier League clash with Everton.

"When you score goals I think it helps for happiness to be back. As an attacking player you can play very, very well, but if there are no goals then the happiness is not there."
