One year after Chelsea sacked Jose Mourinho, we look at the differences between his title-winning side in 2014/15 and Antonio Conte's team.

Two years ago, Chelsea hogged the Premier League summit from the first day of the season and were three points ahead of Manchester City after 16 games with 12 wins, three draws and one defeat on 39 points.

This season, despite an underwhelming start under new boss Antonio Conte, the Blues are six points clear of Arsenal on 40 points after the same number of games with 13 wins, one draw and two defeats.

Following a disappointing September, Conte changed Chelsea's formation to 3-4-3 against Hull in October and the Blues have won every one of their 10 games since.

But what is difference between Conte's revitalised Chelsea and Mourinho's title-wining side two seasons ago?

Attack

Diego Costa and Eden Hazard have once again hit form this term, surpassing their key stats from the same stage in 2014/15 with 20 goals and six assists between them.

However, one notable deficiency compared to two years ago is a lack of aerial threat, which was provided in 2014/15 by out-of-favour John Terry and departed Didier Drogba.

Drogba returned to Stamford Bridge on a free transfer in July 2014 but was limited to eight starts and 856 minutes during the campaign.

During his limited game time, the Ivory Coast striker won nearly five aerial duels per 90 minutes, more than any other Chelsea player, scoring two headers.

Chelsea's only deficiency this season appears to be a lack of aerial threat

This season, Chelsea's leading regular forward for aerials is Diego Costa with just 0.96 won per 90 minutes, despite being 6ft 2in, and the Blues have not scored one header.

Elsewhere across the pitch, Chelsea are creating a similar number of goalscoring opportunities and shots compared to two years ago.

However, Conte's Chelsea slightly edge Mourinho's team for goals scored and goals from outside the box, with Costa (two), Hazard, Pedro and Cesc Fabregas all netting long-range strikes this season.

Defence

Despite only playing three orthodox defenders since October, Conte's Chelsea play deeper than Mourinho's side, completing more passes in their own half and fewer in the opposition's half.

Conte's side produce slightly more crosses and dribbles than the Chelsea of two years ago and enjoy an almost identical average of 55.11 per cent possession.

This season, Chelsea are very similar to their team in 2014/15 in several areas but appear to be playing slightly deeper

N'Golo Kante's interceptions appear to be central to Chelsea's success at playing the 3-4-3 system, as they were equally pivotal during Leicester's fairy-tale campaign last season.

Chelsea now make more interceptions than they did in 2014/15

The France midfielder has already made 43 interceptions for Chelsea - more than any other midfielder in the Premier League.

N'Golo Kante's interceptions are pivotal to Chelsea's style of play

By snuffing out passes before dangerous attacks build, Kante has helped reduce the team's need to win duels, tackles and saves, helping to boost the Blues' clean sheet ratio.

Passing and work ethic

The only exception to Chelsea's deeper play emerges down the right flank, where wing-back Victor Moses has become a regular in the side after four years on the sidelines and out on loan.

Victor Moses has balanced the flanks down Chelsea's right

Branislav Ivanovic and Willian occupied the right side two seasons ago but Moses has helped increase activity and balance on the flanks.

Wing-back Marcos Alonso has helped maintain Chelsea's left-side activity this season, the channel Hazard typically occupied in 2014/15 in front of César Azpilicueta - whereas the Belgium midfielder has played a more central role this term.

Chelsea now have more success down their right flank than they did in 2014/15

Chelsea appear to work slightly harder under their new coach this season, covering 112.5km a game compared to 109.5km in 2014/15, and complete 535.3 sprints per 90 minutes compared to 475.5.

Conte's new system relies heavily on wing-backs Alonso and Moses running the lines and Kante hunting down opposition and regaining possession.

The lack of aerial prowess in the box appears to be the Blues' only deficiency this term as Chelsea, spearheaded once again by Costa and Hazard, dominate the Premier League summit after 16 games - as they did two years ago.
