Followed United since the mid '90s, here's my ranking for only the main strikers: 1. Ruud Van Nistelrooy 2. Andy Cole 3. R. van Persie 4. Rooney 5. Ibrahimovich 6. Saha 7. Chicarito 8. Berbatov 9. Lukaku I think Lukaku is the worst United have had (in my following time) as the main striker. It just feels so strange, seeing a United main striker with attributes like him. He has time on his side to prove me wrong though.
