The Serbian feels that Jose Mourinho's Blues are closer to recapturing the trophy than at any point over the past three yearsChelsea defender Branislav Ivanovic believes that his team can mount a title challenge after closing the gap on Arsenal to four points.
After winning the Premier League under Carlo Ancelotti in 2009-10, the Blues have finished nine, 25 and 14 points behind eventual champions Manchester United, Manchester City and United again, respectively, in each of the past three seasons.
Chelsea have only lost two league games so far this term and extended their unbeaten home league record under Jose Mourinho to 67 matches with a 3-1 victory over Southampton on Sunday.
"This is our best chance [to reclaim the title] but we have to be careful," Ivanovic told the Daily Star. "We must carry on this way and fight for every game and every point.
"At this stage in the years before, we would always be trailing by a lot of points but we are up there now and this has given us an opportunity.
"It's a good thing when you go into each game feeling you are there and right at the top. We have improved as a team but we have to show it in every game."
Ivanovic has started every Premier League game for Chelsea this season, scoring one goal and contributing to four clean sheets.
