We did all right in the one-day series but here we are disappointed," Tharanga said in the post-match news conference yesterday. <p></p> <p></p>In their 100th T20I appearance, the Sri Lankan innings folded in 16 overs after <a href="https://www.cricketcountry.com/news/yuzvendra-chahal-becomes-highest-wicket-taker-in-t20is-in-2017-671788">man-of-the-match Yuzvendra Chaha</a>l triggered their collapse with a 4/23, before Hardik Pandya ripped through the tail claiming 3/29. <p></p> <p></p>"I am very disappointed with the way we batted. We should have batted 20 overs. Losing is okay but we have to get close to the target. The main thing is we could not compete." <p></p> <p></p>"While bowling, we started well but in the middle and death overs we gave too many boundary balls and momentum shifted to India," Tharanga said. <p></p> <p></p>Asked whether the team was missing senior players, Tharanga said it was the best possible squad available. <p></p> <p></p>"This is the best team at the moment. We missed a lot of players because of injuries in the last few series but everyone is here. <p></p> <p></p>"I do not think we are missing anyone. It is about being consistent in all the three departments -- batting, bowling and fielding," he said. <p></p> <p></p>Tharanga also revealed that former Test cricketer <a href="https://www.cricketcountry.com/players/thilan-samaraweera/">Thilan Samaraweera</a> helped him with his batting techniques and the left-hander has benefited from the advice. <p></p> <p></p>"Samaraweera has played a lot of cricket with me. He has seen me batting from the close quarters and he said I should change my batting stance." <p></p> <p></p>"He asked me why I changed my foot movement. Now with my new batting stance, I am getting a bit of rhythm and the credit goes to Thilan," Tharanga, who scored a 82-ball 95 in the third ODI in Visakhapatnam, said. <p></p> <p></p>Having lost the Test series 1-0, Sri Lanka faced a 1-2 defeat in the ODIs and trail 1-0 in the T20Is. <p></p> <p></p>The second and third T20Is of the series are slated in Indore (December 22) and Mumbai (December 24) respectively.
