New signing has confidence that the club can move up the Premier League table

The powerful Nigerian striker has joined the Hammers on a season-long loan from Inter and made his debut in the 3-1 defeat against Chelsea at Upton Park on Saturday.

The 23-year-old was named man of the match for his efforts, but acknowledged afterwards that the players are far from happy with their start to the season.

“It is not a very good atmosphere (in the dressing room). Everybody knows what is going on and obviously we want to do well and make sure we start winning games, which is the most important thing,” he said.

“I believe we can win three games now, but we have to start to take one step at a time and I believe starting at the next game against Stoke (on Saturday) we just have to do everything.

“They are in the same situation that we are. I believe it’s going to be a tough game but we have to win. We have to go back and improve on our mistakes and make sure we don’t repeat the same thing and score goals.

“I believe the next game I have to improve in terms of scoring. Football is all about scoring goals. Next game we have to do more to make sure we win.”

Finding the net has been a problem for West Ham so far this season and Obinna’s strike partner at the weekend, Carlton Cole has yet to find the net, but the forward was keen to praise the England international and is confident the pair can strike up a fruitful partnership.

“He’s a very good striker, who is very strong and good with the ball. He knows how to keep the ball, knows how to play one twos and play good passes at the right times,” he said.

“I really enjoy playing with him because I find it easier to operate with him flicking the ball down, for me to go past him to pick up the ball. We have to keep practicing more and more, I just arrived this week I haven’t had much time to practice with him.

“So many of the guys that played today are new and its not easy playing with a new team, we have to put that understanding together and work towards what the manager wants.”

Obinna is one of eight new players brought to the club by boss Avram Grant in the off-season and after a frustrating time at Inter, playing only nine times since joining in 2008 and the striker is delighted to be given the opportunity to show what he can do.

“I wanted to come over, I wanted to come to play in the Premier League. This is the kind of game that I want to play, when the manager wanted me and he asked for me if I was ready to come and play I said yes, I want to try,” he said.

“I’m happy to be a West Ham player I believe we have to work hard to take West Ham where it belongs.”
