The Delhi team lost their fifth overall match in the tournament to languish at the bottom of the points table with just four points from seven outings.
"It''s difficult and pressure is on us. We have to pull ourselves and really bat and bowl in coming games," Sehwag told reporters at the post-match press conference.
But the skipper sounded optimistic and said they still have an outside chance of making it to the next stage.
"Nothing is impossible. We can still back ourselves from here on and if we win two three games from here on, then it''s possible for us but yes it''s quite difficult," Sehwag added.
Kolkata Knight Riders comprehensively beat Delhi to notch up their fourth win in the IPL while Delhi suffered their fifth loss in the tournament and their road to recovery from here on looks pretty bleak.
Sehwag added that he has to back his own performance in order to turn around Daredevils'' fortune.
"I have only got one fifty in the seven games. So I need to look at my performance also. If I get going it will be difficult for other teams to come back," the Delhi skipper said.
"I''ll have to shoulder the responsibility and need to stay at the wicket for 12-15 overs. It will be good for my team," he said.
Sehwag defended his decision to send Travis Birt ahead of in-form Y Venugopal Rao, saying, "We thought a left-hander would be a better option against left-arm spinner. But nothing seems to be going our way."
"None of our plans are working. T20 game is like that only. Probably we will send Venu and Naman Ojha up the order in the coming games," he said. .
