With Paul Scholes having retired, Ferdinand only trails Giggs in the medal stakes, and that motivates him to secure further success when the Wales legend finally hangs up his boots.
"I'm not happy with what I have won, not when I can look around at people in the changing room and know they have got more than me," Ferdinand said.
"You always aim for the people above. That is what I did the day I walked through the door. I looked around and saw people with three, four, five titles and thought 'I want to have that'.
"You set yourself targets all the time. I am never going to sit in that changing room and think 'I am happy with what I have done'."
