Manchester United veteran Ryan Giggs credits their slow start to the season due to bad luck.
Chelsea are already four points clear of United and Giggs admits they cannot afford to let them extend that further.
He said: "That's probably been the case over the last six or seven years, so we're wary of that."
He added: "I honestly feel we just haven't had the breaks.
"The concentration lapses are a concern, but we're not too far away.
"If we finish our chances off, we will be beating teams four or five nil."
