In charge of a young team, Raina lost his first match as a captain against Zimbabwe and the side crashed out of the tournament after suffering three defeats in four matches.
"We haven't looked good throughout the tournament," Raina said after India's six-wicket defeat to Sri Lanka [ Images ] here.
Talking about the match, Raina felt the bowlers let down the team.
"I am not happy at all. We scored around 270 but we didn't bowl well, especially with the new ball. R Ashwin bowled well, and he batted well too," he said.
"All credit goes to Sri Lanka, they batted really well, especially (centurion) Dinesh (Chandimal)," he added.
Sri Lankan captain Tillakaratne Dilshan [ Images ] was happy to have sealed a place in the final with one match to spare.
"I said in the morning, we want to finish it off today. Our players did really well. We kept the pressure up through the fielding, keeping the fielders up," Dilshan said.
"I told the players we needed to improve the fielding, and they did a really good job in the field, stopping good shots, taking difficult catches. I'm really happy with Chandimal's batting, playing so well in his second game," he said.
