The Reds have drawn seven times this season, leaving them five points off the top four.
"We have lost too many points at Anfield and have to improve our home form," the left-back said.
"We have to stay positive because, maybe the Swansea game aside, we have deserved to win the others we have drawn.
"If we start to take our chances then we can be in the top four, but if we don't we'll make it more difficult for ourselves."
Liverpool are currently seventh in the league with 35 points from 21 games.
