A history of Chelsea's Premier League titles
Chelsea will win their fifth Premier League title on Friday if they can defeat Tony Pulis' West Brom at The Hawthorns.
Antonio Conte's side have held on to top spot since mid-December and Monday's win over Middlesbrough ensured they will travel to the midlands knowing victory will see them crowned champions.
Here, Press Association Sport looks at the other Premier League title-winning Blues sides to see how the current crop compares.
2004-05 = 95 POINTS ( W29 D8 L1 GF 72 GA 15)
TEAM: Cech; Gallas, Terry, Carvalho, Ferreira; Makelele, Tiago, Lampard; Duff, Drogba, Gudjohnsen
Jose Mourinho's first season in English football culminated in a record-breaking season as Chelsea topped the table with 95 points, the greatest ever haul in top-flight history.
It was Mourinho's defence, comprising of goalkeeper Petr Cech and a back four of William Gallas, PFA Players' Player of the Year John Terry, Ricardo Carvalho and Paulo Ferreira, that was the real strength of this team as they conceded just 15 times across 38 fixtures, a figure only matched across history by Preston's 1888-89 team when 16 fewer games were played.
Frank Lampard scored twice at Bolton to clinch the silverware and in Damien Duff, Arjen Robben and Eidur Gudjohnsen, Mourinho's side possessed plenty of flair too.
2005-06 = 91 POINTS (W29 D4 L5 GF 72 GA 22)
TEAM: Cech; Del Horno, Terry, Carvalho, Gallas; Makelele, Essien, Lampard; Robben, Drogba, Cole
Mourinho's reigning champions picked up where they left off, winning each of their first nine and dropping just five points in their opening 22 games, at which stage they already had a 16-point advantage over Manchester United, who were beaten on April 29 to ensure the title returned to Stamford Bridge.
It was once more Cech, Terry and Lampard who made up the spine of Mourinho's team along with Claude Makelele and Didier Drogba, while midfielder Michael Essien's signing from Lyon was one of the crucial bits of business conducted the previous summer.
2009-10 = 86 POINTS (W27 D5 L6 GF 103 GA 32)
TEAM: Cech; Cole, Terry, Carvalho, Ivanovic; Mikel, Ballack, Lampard, Malouda; Drogba, Anelka,
The 'Special One' was long gone by the time Chelsea defeated Wigan 8-0 on the final day of the season to lift English football's leading prize again four years after they had previously done so. Carlo Ancelotti was at the helm and promoted a more attacking style as they became the first side to score over 100 league goals in the Premier League era.
Most of the team was leftover from Mourinho's time, including Drogba, scorer of 29 league goals, and first-time title winners Ashley Cole, Michael Ballack and Florent Malouda, with Branislav Ivanovic and Nicolas Anelka the only regulars to have arrived after the Portuguese left in 2007.
2014-15 = 87 POINTS (W26 D9 L3 GF 73 GA 32)
TEAM: Courtois, Azpilicueta, Cahill, Terry, Ivanovic; Matic, Fabregas; Hazard, Oscar, Willian; Costa
In the second season of Mourinho's second stint, he won his third and the club's fourth Premier League crown having only vacated top spot once all term, between their first and third fixtures, after they began with a 14-match unbeaten sequence.
Mourinho promoted promising youngster Thibaut Courtois in favour of Cech as his goalkeeper and acquired Cesc Fabregas and 20-goal striker Diego Costa in the summer having purchased Willian and Nemanja Matic in the previous two windows. He also managed to get the best out of eventual PFA Players' Player of the Year Eden Hazard.
2016-17 = 84 POINTS (W27 D3 L5 GF 75 GA 29) *after 35 games
TEAM: Courtois; Cahill, Luiz, Azpilicueta; Alonso, Matic, Kante, Moses; Hazard, Costa, Pedro
After a disastrous title defence in 2015-16 where they finished 10th, the Blues have been led back to the summit by former Italy boss Antonio Conte using many of the players Mourinho had struggled with just last term.
Conte reverted to a 3-4-3 system to kick-start a 13-game winning sequence from October, with Victor Moses, loaned out for three straight years by Mourinho, a key contributor along with summer signings Marcos Alonso and N'Golo Kante.
The rest of the team were regulars under Mourinho apart from the returning David Luiz, who he sold in 2014 after starting him in just 15 Premier League games the previous term.
