Chelsea defender Branislav Ivanovic has said that he is pleased that the Blues extended their lead at the top of the Premier League with Sunday's draw at home to Southampton.
However, Ivanovic believes that Chelsea can consider themselves unlucky to have not taken all three points against the Saints.
"It was a hard, difficult game," the Serbian told the club's official website.
"In the second half we tried to give our best, we created some chances but we didn't score. I think with a little bit more luck we could have got three points.
"We played very well in the second half and controlled the game."
Chelsea travel to Hull City next Sunday.
