The Spaniard, who is currently sidelined with a broken rib, has scored two goals in four games for United since he joined the club from Athletic Bilbao in the summer.
While some players from abroad often fail to adapt to the pace of the English game, Herrera insists that he is relishing the challenge.
"The Premier League is a great league," the 25-year-old told the club's official website. "It's a very quick league, non-stop and great spectacle for the fans.
"That's good because sometimes in other countries there are more teams that try to keep the ball in their end of the pitch but in the Premier League you will see a lot of goals."
United return to Premier League action next Monday when they travel to The Hawthorns to face West Bromwich Albion.
