At Harare, Zimbabwe beat an Indian team brimming with an array of Next-Gen stars by 13 runs in the first T20I match of the five-match series.
"Halfway through (the match) we had lost five wickets, and it would've been best for us if I stayed there till the end.
I am very disappointed with the way I got out and the rest of the match panned out," said Gill in the post-match presentation ceremony.
"There was a bit of hope for us. But while chasing 115 and your No.10 batter is out there, you know something is wrong," he added.
India were recently crowned champions in the T20 World Cup albeit with a different set of players.
Gill said the team could not execute its plans. "We spoke about taking time and enjoying our batting but it didn't pan out that way."
He also said India were a bit under-par on the field, despite bowling well to restrict the hosts to 115 for nine.
