Former Manchester United striker Wayne Rooney believes the club still lacks two quality players to compete with elite clubs.Rooney feels Manchester United need another reliable goalscorer besides Benjamin Sesko, and they also need to invest in a quality full-back.

Sesko is still young and still adapting to English football. He will need time before he can become a prolific option for Manchester United upfront. Adding another striker would have been ideal for them this summer.
