On Tuesday, India played hard fought 1-1 draw against much lower-ranked Bangladesh in a Group E Asian Qualifiers tie for the FIFA World Cup at the Salt Lake Stadium in Kolkata.
Taking to Twitter, Chhetri on Wednesday also expressed gratitude to the fans who turned up in large numbers to support the Indian team against Bangladesh.
"We couldn't deliver a performance to match the atmosphere at the Salt Lake last night, and the dressing room is very disappointed about it. We couldn't capitalise on the chances we got, but this is a process on the pitch and in the stands. You turned up, we'll keep attempting to," Chhetri tweeted.
In what was a must win game for the Indian team, Bangladesh took an early lead in the 42nd minute courtesy Saad Uddin. It was only in the final moments of the game that centre-piece Adil Khan scored the equaliser to save the hosts the blushes.
After the game, India head coach Igor Stimac admitted that his team conceded a "silly goal" against Bangladesh and that they have a lot to work on ahead of the next set of matches.
"Bangladesh were resilient. We did not react well and conceded a silly goal. India is trying to play modern and technical football. There is still much more to do," Stimac told reporters at the post-match press conference.
Backing his young players, the Croatian 1998 World Cup bronze medallist said: "We need to stay optimistic. We have shown we have confidence to play against anyone."
