Former Manchester United and Liverpool striker Michael Owen believes Red Devils forward Marcus Rashford lacks a 'killer instinct'.
Following the departure of Romelu Lukaku to Inter Milan last month, Rashford and Anthony Martial have become United's men upfront this season.
Both strikers are sitting on two goals after four Premier League games this season, but Owen feels Rashford is not obsessed with getting goals.
“I don’t think scoring goals is what he goes to bed craving, "Owen said at the launch of his autobiography, Reboot.
“I think it is overall performance, chipping in with goals, assists, everything. He is a better all-round player than me.
"He has a great touch and all round skill that I never had, but he hasn’t got the killer instinct that I had.
"I was just obsessed. Players like Robbie Fowler, Sergio Aguero or Harry Kane - these people who are obsessed with goals. I don’t think he is obsessed with goals.”
