The Hammers are rooted to the foot of the table after just one win from 13 matches but Avram Grant feels they are doing the right things to turn promising performances into maximum points following home draws against West Brom and Blackpool.
Next up is a trip to Liverpool and Nigeria striker Obinna - on a season loan from Inter - feels the Irons are not far away from getting everything together.
"We have to speak to ourselves and try to improve," the 23-year-old told WHUTV.
"We can all say that we play good football, but when you play good football and you don't win, sometimes it doesn't work.
"Sometimes you have to play badly and win and I believe our time is coming."
West Ham were somewhat unfortunate not to be given at least two penalties by referee Kevin Friend during the first half against Blackpool, one when Obinna's goalbound effort struck Craig Cathcart on the arm.
The striker, however, maintained even though everything may appear to be against the Irons, the squad must keep focused.
"Things like this do happen. Sometimes you are lucky and sometimes you have to play simple to be able to score," he said.
"When things are like this, it's getting bad, but we have to show that our heads are high, we are more united and if we speak to ourselves mentally we will win games and we will be okay."
Obinna challenged his team-mates to provide the perfect response at Anfield.
He said: "It is about mental stuff and we just have to psyche ourselves up, speak more to ourselves, be more united and we are definitely going to get out of this place.
"Football is my passion, football is what I love and it is also my job.
"I have to face anything that comes out of it, whether good or bad, and the most important thing is that you give 100%, you give your maximum and you come out with your heads held high.
"We have to give more."
Some sections of the Upton Park faithful again called for Grant's dismissal at the final whistle on Saturday but Obinna believes it is up to the players to get them back on side.
"We deserved to give more to our fans because they've been really cheering us up and making sure, week-in and week-out, that West Ham win games," he said.
"We need more of their support, we need them to be behind us and together we will get out of the position we are in now."
As well as having striker Carlton Cole in the senior England squad, West Ham youngster George Moncur was on Tuesday drafted into the Under-18s group for the evening friendly against Poland at Wycombe.
