Scarlets captain Matthew Rees has called on his team-mates to be more consistent, as they approach the final three games of the season.
Rees, 31, has not ruled out a top four finish in the Magners League ahead of the clash with Munster at Parc Y Scarlets on Saturday.
But the experienced Wales hooker already has his sights set on improved performances next term.
"We have to make sure we're in that top four throughout the season," he said.
Rees, who has 47 caps for Wales, believes individual mistakes have hampered the Scarlets this season.
"If you look back at the games that have cost us points it's been down to a fine margin," said the Scarlets skipper, whose previous clubs include Merthyr, Pontypridd and the Celtic Warriors.
"We've had errors that have cost us points and could cost us a place in the top four."
Scarlets will travel to Glasgow Warriors on 22 April and will round the season off with a home derby against Cardiff Blues on 6 May.
But it is the game with table-toppers Munster that the Scarlets are focused on for now.
"Making the top four is crucial," added Rees, who has three caps for the British and Irish Lions.
"Looking back over the season, we played Munster out there and I think it was a game we could have won - but yet again a couple of individual errors have cost us again.
"But we were in that game for long periods of time and that's given us confidence this week building on a performance ready for Saturday."
Rees remains confident that his team can make the play-offs, and is predicting an exciting finish for Scarlets supporters.
"It could go down to the wire with the Blues game at home, which would be a great finish to the season," he added.
"A couple of results haven't gone our way but we're still in the running with three games left.
"We must win on Saturday."
