The midfielder has struggled to be a regular starter for the Hammers this season.
The midfielder arrived as one of several summer signings by manager Slaven Bilic, as they secured him for an undisclosed fee from Sampdoria.
So far he has struggled to be a regular for the Hammers, with a series of niggling injuries having limited him to just 761 minutes of action in the Premier League so far.
Aside from that, the midfielder also admits that he struggled with the language barrier upon his arrival at Upton Park.
“I am really very happy for the team and for myself, especially given these recent results. When I play, I am always happy!” he told whufc.com.
“At the beginning I had some problems with the language because, while I can speak Spanish and Italian, I didn’t speak any English at all, but now I am improving so it is better.
“The style of football in England is completely different to Italian football, so everything was completely new but I am getting used to it and every day I am getting better. I now understand how English football works!”
The Hammers will now be hoping he can play a big part in the final part of the season as they hunt down a place in Europe next season.
They are currently in the hunt on two fronts; with the East London outfit firmly in the race for a top six place in the Premier League as well as currently finding themselves in the fifth round of the FA Cup.
Manager Slaven Bilic will need a full squad at his disposal to remain competitive and Obiang will surely be keen to play his part in the run in.
