The Nigerian has bemoaned club's poor start to the season
The 23-year-old struggled to get first team football in Italy and joined the Hammers in the summer on a season-long loan. However, the striker has endured a difficult start to his West Ham career with the club fixed to the bottom of the Premier League table.
Although the club remain in the relegation zone, recent performances — including a 4-0 victory over Manchester United in the League Cup — have indicated that they have the quality to mount a successful survival bid.
Obinna has been ever present in the West Ham team since joining on loan and the Nigerian has told the club's official website that he has enjoyed his time in London and is hoping to maintain recent form to earn a permanent move to the club.
"I've been having a wonderful time since the beginning and like I said from when I was first here, football is going to speak for me - not saying I'm going to do this and do that,” Obinna told the club's official website.
Obinna has admitted that West Ham’s poor start to the season has left the club with an up-hill struggle for the rest of the Premier League campaign after taking only 12 points from 17 games.
"We didn't start very well," he added.
“Losing the first four games was not good and really affected the team.
"Gradually we've been trying to pick up wins but it's not been easy.”
Obinna has only scored three goals in his 16 appearances for the Hammers but he has been a popular figure with the West Ham supporters since joining on loan from Inter.
