The Spanish midfielder moved from Sampdoria to West Ham.
The Spanish Under-21 international said: “It’s a fresh start. I leave an environment that knows me well and that gave me so much, and arrive in another that does not know me at all, and which represents something completely new.
“In Sampdoria I have been great, but I always had the idea of the Premier League. I had decided that I would leave this summer.”
Obiang arrived at the Boleyn Ground last week, and he is expected to stake a claim as part of Slaven Bilic’s starting XI.
He is an all-action defensive midfielder, and the type of player that West Ham did not possess prior to his signing. The likes of Cheikhou Kouyate and Alex Song - who has now returned to Barcelona - were both classy players, but they lacked the energetic stye of Obiang.
Arriving as a budget signing, Obiang is sure to be a success, and agreeing a deal with the 23-year-old is a strong statement of intent from the Hammers, and proof that they can bring some of the most high-rated European players to East London.
Obiang has admitted that he was interested in a move to the Premier League for a long time, and the chance West Ham have given him is one he was unlikely to turn down.
They have ambitions to move into the upper echelons of the league table, and will be looking to utilise their chance in the Europa League as a statement of their European credentials.
With Obiang now patrolling their midfield, the chances of them establishing their status has just become much, much easier.
