Andrew Strauss says he is frustrated by his own form, after seeing his England side lose the first Test to Sri Lanka by 75 runs.
Jonathan Trott's century proved in vain, as England lost six wickets for 31 runs and were dismissed for 264.
The England captain has scored just one century in 48 Test innings and admits that he is feeling the pressure.
"It is frustrating. I am hitting the ball really well, getting to 20 but not going on," he said.
"It is important that I do in the second game of the series."
England, who could be without bowler Stuart Broad for the second Test because of a calf problem, have lost all four of their Tests in 2012, having gone down 3-0 to Pakistan in the United Arab Emirates.
Strauss, who has scored 32, 56, 26, 26 and now 27 in his last five innings, has gone 23 innings since his last Test century, against Australia in the first Ashes Test in Brisbane in November 2010.
That century ended a run of 24 innings without a ton, going back to the hundred against Australia at Lord's in July 2009.
Strauss attributed the defeat in Galle to a series of mistakes, both with the bat and in the field. The most glaring were the two dropped catches by Monty Panesar on the first day.
The spinner put down Mahela Jayawardene twice in the final hour, firstly on the square-leg boundary off James Anderson with the Sri Lanka captain on 147 and again at mid-on off the bowling of Broad.
However, Strauss insisted Panesar would recover from the setback.
"He is very disappointed and down with himself for dropping those catches," Strauss told BBC Test Match Special.
"But we are human - we all make mistakes. We are all behind him because we win together, and we lose together."
The one positive that Strauss took from the final day was a seventh Test century for Trott, who faced 266 balls before he was caught at leg gully by Tillakaratne Dilshan off the bowling of Suraj Randiv for 112.
"The way Jonathan Trott performed was outstanding," he said. "He showed a combination of technique and application and skill to get that hundred.
"It was an incredible combination of the attack and defence that you need to score runs in these conditions. He did not deserve to be on the losing side.
"For a while there, it looked like we would pull off the unlikely, but ultimately we left ourselves with too much to do."
England's target was inflated by the 87 runs put on by Sri Lanka's final two wickets in their second innings, a late rally Strauss' counterpart Jayawardene suggested helped turn the game.
"[To set] 340 was a bonus," he said.
"I thought 275 would be competitive so with 340 we had the luxury of 40 or 50 runs. That gave the impetus to the bowlers who were much more relaxed going out there and bowling to the English batsmen."
Jayawardene, who praised Trott's innings, added that the win showed his side's development after a run of eight home Tests without a victory since Muttiah Muralitharan's retirement in July 2010.
"It's been a bit of a tough period for us trying to get things right," he said.
"The boys worked really hard trying to get things right, everyone's been trying to improve as a unit and today we showed lot of character."
The second and final Test starts in Colombo on Tuesday.
