Leaking drivers door

Hi All, founding I've got some water coming in on the bottom of my drivers door on my 2004 discovery. Thought it was the door rubber do changed that but still no joy. Anyone got any idea how the water is getting in as there doesn't seem to be any water running down anywhere. Many thanks for your advise in advance
