Fernando Torres insists there's nothing unusual about Chelsea's inconsistent results.
The Spain striker says manager Jose Mourinho's tactics will take time to bed in.
Torres, who has started only one Premier League game, said: "A new manager always brings a different style and different ideas.
"We have been asked to achieve something fast, but it takes time.
"Manchester United and Manchester City also have a new manager, so they are in exactly the same situation. It is not an excuse, but it takes time.
"We are working game by game and every one is getting better."
