From there a month later he was sent to Fulham (the Cottagers, who play at Craven Cottage), which paid £25,000 to the Clarets. At Fulham, teammate Alan Mullery noted that he thought Mellor had literally broken every finger on both hands. Mellor was to make over 220 appearances for Fulham in all competitions over six seasons from 1972 to 1977, including perhaps most memorably an appearance in the 1975 FA Cup Final, during which he was unfortunate enough to be deemed at fault for West Ham's two goals, both scored by Alan Taylor.
