Ferdinand believes experience could be the key to landing the title.
"(Having title experience) is huge," he told Sky Sports 1. "We've been in this position before so that counts for a lot.
"We know what it takes to get over the finishing line first and we have to use that experience to do it again.
Ferdinand was also satisfied with the performance against QPR.
"They had a man sent off early in the game, and while we would have liked to score a few more goals, a clean sheet and a couple of goals - we would have taken that before the game," he said.
"We never doubted ourselves that we could put together a run of good games.
"Momentum is key at this stage of season, we can tick one more game off today and hopefully we can keep it going."
