Which Chelsea Premier League winner improved most?

Chelsea completed a dramatic turnaround from last season's poor performances to lift the 2016/17 Premier League trophy on Sunday.

At an emotionally charged Stamford Bridge, Chelsea were handed their well-deserved Premier League title, as John Terry bode farewell to the home support.

It marked a significant improvement on a dire 2015/16 campaign, which saw them finish 10th after a disastrous start to their title defence. Those performances saw Jose Mourinho relieved of his duties at Christmas before Guus Hiddink steadied the ship.

Under Antonio Conte this season, Chelsea set a Premier League record of 30 wins in a single season. With that in mind, WhoScored.com run through Chelsea's most improved players using their stats-based rating system.

To qualify, players must have made 20 or more appearances across both league campaigns...

Victor Moses has been Chelsea's most improved player this season. While he spent last season on loan at West Ham, Moses played a vital role for Chelsea at right wing-back this term. Many had tipped the Nigerian to be shown the Stamford Bridge exit on the back of a succession of loan spells, but he became a key man under Conte following the switch to a back-three. Indeed, the Blues lost only two of the 29 league games Moses started this season, with his WhoScored.com rating increasing by 0.71, the most of all Premier League players to make 20+ appearances over both seasons.

Quickly following suit is Eden Hazard, whose WhoScored.com rating (7.81) was better than any other Premier League player this season. After ending last season strongly after struggling with injury during the dying embers of Mourinho's second reign at Stamford Bridge, Hazard continued to astound this term, noted in the WhoScored.com rating improvement of 0.70, with 143 successful dribbles - the second best return this season - contributing to that huge upturn in form.

Like Moses, Marcos Alonso was another who benefited from Conte's change to a three-man defence, with the Spaniard registering 30 league starts following his deadline day arrival from Fiorentina. The 26-year-old gained a respectable WhoScored.com rating of 7.07 with the Viola in his final full campaign in Italy, yet that shot up to 7.40 with the Blues this season. Six goals and a further three assists from left wing-back signified Alonso's importance for Chelsea in the final third as he built up an impressive rapport with Hazard down the Blues' left flank.

After a barren run, there was a time when it seemed as though Diego Costa would fail to break the 20-goal barrier, but a strike in the 3-0 win over Middlesbrough ensured he met the target for the third time in his last four league seasons. Following an indifferent second season at Stamford Bridge, Costa proved his worth to the west London club with a WhoScored.com rating improvement of 0.32.

Gary Cahill - Rating Change +0.25

After an underwhelming campaign for the Blues last season, Gary Cahill's rating improved by 0.25 this time out, with the England international another beneficiary from Conte's swap to a back-three. Indeed, he averaged far more passes per game this season (50) than last (33.6) as the 31-year-old returned to his consistent best to ensure Chelsea ended the campaign with the third best defence having conceded just 33 goals over the 38 matches.

Chelsea's Mr Reliable, Cesar Azpilicueta became just the fourth outfielder to play every minute in a title-winning campaign, with his exploits recognised via a player-of-the-year nomination. The 27-year-old was vital in Chelsea's three-man defence, while his versatility across the pitch saw him start in no fewer than four positions over the season. Like Cahill, Azpilicueta's passes per game increased on the previous campaign (48.6 to 64.6) as the Spaniard quietly impressed in another season in west London.

While Hazard was granted the freedom to roam in the final third, Pedro's defensive contribution proved vital down the right and allowed Moses to break forward and stretch opponents. Following an indifferent debut campaign in England, the Spain international proved his worth for the Blues with a series of mature displays in attack, as his tackles per 90 minutes rose from 1.6 to 2.0.

Thibaut Courtois continues to excel between the Chelsea sticks and ended the season with the most clean sheets (16) in the Premier League, that return a vast increase on the five attained last term. What's more is that his save success rate rose from 65.3 per cent to 70.1 per cent, that contributing to a WhoScored.com rating increase of 0.08.

Many had tipped Nemanja Matic for a move away from Chelsea over the summer in the wake of N'Golo Kante's arrival from Leicester, yet the Serb registered 30 starts under Conte, with his WhoScored.com rating improving marginally by 0.04. His seven assists was a significant improvement on two the previous campaigns, while passes per game increased from 48.7 to 53.3 as Matic established himself as a key man for the Blues once more.

A deadline day arrival like Alonso, David Luiz's return to Stamford Bridge was treated with derision as Chelsea failed to land a number of top targets before plumping for the Brazilian. However, the critics were quickly silenced as Luiz slotted seamlessly into the back three under Conte. His rating for Chelsea this season was the same as with PSG last term (7.16) as the 30-year-old displayed a remarkable level of consistency not shown in his first stint in the capital.

Cesc Fabregas - Rating Change -0.10

Despite a lack of game time, Cesc Fabregas still managed to register 12 assists this season, a return that was in fact better than last season. That being said, the midfielder made just 13 starts in Conte's debut campaign, with the dip in first-team action seeing his WhoScored.com rating drop by -0.10. Indeed, tackles per game dropped from 2.8 to 1, as did passes per game (76.5 to 45.8).

Like Fabregas, Willian was a victim of a lack of game time as his WhoScored.com rating dropped by 0.31. The Brazilian lost his starting spot to Pedro early in the season and was never able to win it back. That being said, the attacker was a key man for the Blues as his eight goals and two assists suggests.

Despite his influence in the middle of the park for Chelsea, N'Golo Kante's WhoScored.com rating fell by 0.38 from last season, though that in part says more about his impact in the Leicester midfield last term. The France international was a one-man wrecking ball for the Foxes, with their counter-attacking game meaning his influence was vital. In a team that enjoyed a larger share of possession, Kante still excelled, as he averaged 3.6 tackles and 2.4 interceptions per game, though both of those dropped from 4.8 tackles and 2.9 interceptions per league match last season.

The man who secured the title for Chelsea with his late goal against West Brom mustered 20 appearances in his debut season, yet 19 of those were as a substitute . He returned five goals and one assist, yet compared to his final season for Marseille, where he bagged 17 goals and registered five assists, his WhoScored.com rating fell by 0.59. Nonetheless, having netted the title-winning goal at The Hawthorns, Blues fans are unlikely to be too downbeat at the sheer drop in rating.
