The former Australian batsman -- who guidedSri Lankato the World Cup title in 1996 -- said his team had been consistent and competitive in all matches.
"It would have been the icing on the cake to have beatenIndiaand go on to win the cup. We made some mistakes but were in the game late in the second 50-over block," Whatmore told AFP.
"It was just one of those games that makes you analyse more."
India's Virat Kohli smashed a career-best 183 to helpIndiachase down a daunting 330-run target butIndiafailed to make it to the final.
Whatmore, who also helpedBangladeshreach the latter stages of the 2007 World Cup held in the Caribbean, praised the Asia Cup hosts.
"Bangladeshhad a really good Asia Cup. On the evidence of this tournament, everyone would agree they have improved. They need to be consistent now," he said.
Whatmore backed Misbah-ul-Haq after thePakistancaptain came under pressure over the team's 4-0 whitewash againstEnglandin a one-day series last month.
"I wasn't aware Misbah was under pressure prior to the Asia Cup. He has some wonderful qualities as a captain and contributed well to our overall performance," said Whatmore, who played seven Tests forAustralia.
Pakistan's next assignment is a tour ofSri Lankastarting in May before taking onAustraliain a five-match one-day series later in the year.
