Jose Mourinho insists Manchester United lack “killers” in front of goal, and has indicated that he wants more firepower.

United are the lowest scorers among the Premier League’s top seven, and have 23 fewer goals than Liverpool.

Mourinho backed Marcus Rashford to come good again next season, but insists United need a poacher like former club favourite Javier Hernandez, who was allowed to join Bayer Leverkusen two years ago.

“We have some players that are not really players in love with the goal,” said Mourinho ahead of Sunday’s trip to Sunderland. “They are good players, but naturally they are not the kind of guy that is a killer.

“I give a simple example. In the way we play at Old Trafford, in the way we dominate opponents and the way we play in the box, I think Chicharito (Hernandez) would have 20 goals easily.

“He is the guy that is a natural. The ball rebounds here, rebounds there – boom! Goal! The goalkeeper saves. Boom! Goal. The cross is coming, he anticipates the first-post header. Goal!

“We don’t score enough goals for the way we play, and the teams that come to Old Trafford, they know that. They feel that.”
