Stuart Broad admits England have lessons to learn from their failure to defend their World Twenty20 title.
A 19-run defeat to hosts Sri Lanka ensured the defending champions depart at the Super Eight stage, missing out to the West Indies on net run rate.
Top-order failings again proved costly as Lasith Malinga (5-31) took three wickets in his first over as England finished on 150-9.
The England skipper told Sky Sports: "We're really disappointed, but the guys have tried really hard in these few weeks here.
"But we've learnt a huge amount and as long as we can take lots away from it, that's all we can ask.
"We need to keep wickets in hand at the top, today proved we've got good strikers at the end who can get us close.
"Obviously losing three in an over hurt us quite a bit - any time a bowler takes five wickets against you in Twenty20 he's going to come out on the winning side.
"Also our death bowling, we didn't get that quite right and that's something we need to work on.
"Samit Patel (67 from 48) played the spinners well and got us in a position we could possibly have won the game from."
Kumar Sangakkara, Sri Lanka's captain for the day as regular incumbent Mahela Jayawardene had a warning hanging over him due to slow over rates, paid tribute to man-of-the-match-Malinga.
"He's a fantastic bowler, he relishes the pressure - both in the Super Over against New Zealand and then here with five wickets," he said.
Sri Lanka had earlier piled up 169-6 in their 20 overs, thanks in the main to Jayawardene (42), Angelo Mathews (28) and Thisara Perera (26).
Sangakkara said: "The guys played really well, we played six batsmen with a couple of all-rounders and backed our bowlers to restrict them and get us wickets.
"It was a great start by the openers and Angelo Mathews, Jeevan Mendis and Thisara Perera finished it off."
Asked about the prospect of lifting the trophy on home soil, he added: "It would be fantastic if we can, but the focus is to keep our feet on the ground and prepare well for our next game."
