Mourinho has confidence his side, whose last league loss was to Sunderland in April, will not suffer an alarming form dip and believes it would take something special for the Blues to be dethroned.

“It would take some other clubs winning every match,” he said.

“With my team, I don’t believe in bad periods. I believe in a defeat. I believe that there are many, many difficult matches ahead of us, so many points to lose. I believe in that.

“But I don’t believe in bad moments. The team is a good team, a solid team. The players know what they want and how to reach it.”

Mourinho is so happy with Chelsea this season that he has permitted a Christmas party.

A miserly Mourinho cancelled last year’s festive shindig, with then-Blues defender Ashley Cole attending Arsenal’s party instead.

The Portuguese has given the go-ahead for a family party despite a hectic schedule of nine matches in a month, beginning at the Stadium of Light today.

He said: “There are Christmas parties and ’Christmas parties’. This one I think the families deserve and the boys are very happy to be with their families.”

The established perception is that Mourinho’s teams are defensive, but the current Chelsea side are apparently breaking the mould.

Mourinho insists he merely works with the players at his disposal.

He said: “I’m not a philosopher. I’m not somebody who sells smoke. I try to be objective, I try to be a coach, which is what I am.

“Lots of people (sell smoke). Not just managers. Lots of people in the world: politicians. They are experts.

“In this moment in my country we have the former prime minister (Jose Socrates) in jail. Imagine how much smoke he sold.”

Mourinho does not expect perceptions of his teams to alter.

“At Real Madrid we scored 126 goals and we were a defensive team, so I don’t think I have a chance to change the perception,” he added.

“Every ingredient has a space when you are cooking a team. You need a bit of flair, yes. But you cannot lose the work-rate, the objectivity.

“You have to be defensively solid and strategic in some matches. In some matches, the percentage of strategy has to be higher than the other ingredients.

“At this moment I have a group of players who have these natural qualities, this natural talent and creativity.

“I adapt to it and I try to build a team where their qualities can flourish.”

Mourinho hopes gifted players like Eden Hazard and Oscar can enjoy success, if not this term, then in future.

He said: “Sometimes you can enjoy your talent but you don’t know what you need to win, but this team has had an evolution.

“Do they have enough to win a title this season? We all hope so.

“Winning or not, next year we want to be a better team than we are this year.”

And with all that considered, he has no intention of delving into the winter transfer market in January.

He added: “I don’t want people to leave. I don’t want people to come in.”
