Manchester United playmaker Henrikh Mkhitaryan is confident that his teammate Romelu Lukaku will continue his goalscoring exploits in the future.

The Belgian, who has arrived in a £75m move from Everton, scored a brace on his league debut for United as they defeated West Ham 4-0 on Sunday.

When asked about Lukaku's league debut for United, Mkhitaryan said: "It's his job to score goals. It doesn't matter how you score.

"The important thing is to score goals. He is going to score goals and he is going to help us."
