"It was a dream come true to make the move to the Premier League," he told the club's official website.
"Every day is a big challenge, nothing over here is guaranteed to you as a player. You have to prove yourself on a daily basis and I think that is one of the major differences from the MLS.
"No-one is different from another guy in the squad, there is no special treatment or perceived level of status, you are rewarded with how you train and play in games and that's how it should be.
"The coach treats everyone equally in terms of his expectations and demands, which are very high and I know I have to work hard to match these, which I am willing to do."
