Mark Warburton spoke of his disappointment after a 1-0 defeat at Stoke effectively ended any chance of QPR snatching a play-off place.
Manager Warburton faces the axe after a dismal end to the season which has seen his team tumble out of the promotion race.
He admitted: “It is frustrating because the team were in a really strong position and we’ve let ourselves down in certain games.
“There’s no doubt about the quality of the players but we have to be more consistent.”
Warburton hopes Rangers can at least better last season’s points total of 68.
To do so they will need to win both their remaining matches of the season, against Sheffield United and Swansea.
“The first thing is to beat last year’s points total,” Warburton said.
“We got 68 last year and finished ninth, two points off seventh, and this year we want to beat that total.
“We have to beat Sheffield United and beat Swansea to achieve that.”
