Benitez said: "When you bring in players from abroad, it always takes time for them to get used to the game in England.
"We cannot play long balls when we have Mata, Hazard and Oscar in our team. Torres isn't a target man so we have to play the ball on the floor.
"We are a team that has to pass. You cannot change the characteristics of your players.
"Technically we are better than some teams but maybe they are physically stronger."
