Manchester City succumbed to a shock 2-1 defeat against Newcastle on Tuesday, but Klopp's men failed to fully capitalise, dropping two points themselves in testing weather conditions on Merseyside.
Liverpool are now five points clear of the defending champions with 14 games to go, but Ferdinand suggested that the title pressure is already getting to them at this early stage.
“That is something Klopp will have to address. You don’t want to see nerves at this stage, this is early.
“I think they looked nervous, the crowd were nervous and it fed into the players."
Next up for Klopp's side is a trip to West Ham on Monday, before a home clash against Bournemouth five days later.
Manchester United await thereafter on February 24 at Old Trafford, as the tough fixtures begin to pile up for Liverpool at the business end of the season.
Klopp and his players still have a long way to go and with each passing week the pressure will continue to build, but they are still in pole position and will hope to further build on their five-point lead at the top.
