Former Blackburn defender Samba was a surprise addition to the QPR squad on the final day of the January transfer window, moving from Russian on a four-and-a-half-year deal worth a reported £100,000 a week.
He made his debut in the
goalless draw against Norwich,
QPR's fourth clean sheet in five league matches.
But their defence was torn apart by Swansea two weeks ago and 28-year-old Samba said: "I have nothing to hide - I was very angry. I said what I saw to the players.
"There's nothing worse than feeling full of regret."
QPR were 2-0 down inside 18 minutes against Swansea. Although injury-hit striker Bobby Zamora came off the bench to halve the deficit, the hosts scored two more to run out comfortable winners.
Samba said: "Bobby Zamora showed us what the Premier League is about when he came on.
"I think more of the players should have his attitude: urgency that reflects we have 12 games left and must play every one like a cup final."
