Chelsea are on the verge of winning a second Premier league title in three years but they were not always the dominating they are now.
Some 20 years ago the Blues were a solid side 11th, 14th, 11th and 11th again during the opening four seasons of the Premier League.
However something turned for then and since 1996 though, the West London club have only ever finished outside the top six on a single occasion, that coming during last season's abysmal title defence.
We now take a look at those people who made the force they were before and during the Roman Abrahimovich era.
1. Ruud Gullit
Dutch legend Ruud Gullit took over from Glenn Hoddle who went on to coach England in 1996 and started initially in a player-manager capacity.
Under his reign, Chelsea started buying and playing more foreign imports like Frank Leboeuf, Gianfranco Zola, Roberto Di Matteo and Gianluca Vialli, who would later replace Gullit as boss.
The Dutchman won the FA Cup as manager and he credited as being the man who started something special for the club.
2. Claudio Ranieri
Already a known name in football after stints with Fiorentina, Valencia and Atletico Madrid. He was responsible for signing the likes of Frank Lampard, Joe Cole and Claude Makelele.
The also developed Lampard and John Terry as well as securing Champions League football again for the club.
3. Jose Mourinho
Chelsea's most successful manager of all time can thank Ranieri for his work as much as Roman Abramovich's money and investments.
The "Special One" won two successive Premier League titles in his first two seasons in charge but would only reach the semi-finals of the Champions League.
He would also win two League Cups and an FA Cup during his three years in charge. The Portuguese returned for a second spell less than a decade later, and clinched yet another title before getting sacked as results surprisinly suffered
4. Carlo Ancelotti
Chelsea suffered somewhat after Mou left in 2007 with the likes of Avram Grant losing a Champions League final, Luiz Scolari being a mess and although Guus Hiddink's did provide FA Cup success none came close to challenging for the league.
That woud all change with the arrival of Ancelotti who secured a domestic double in his first season in charge but would get sacked after finishing second in his second season.
5. Roberto Di Matteo
The former Chelsea midfielder will forever be remembered for winning the club its first ever Champions League titlein 2012.
Assistant to Andre Villas-Boas, the Italian replaced the Portuguese halfway through the 2011/12 season and turned their season around.
Di Matteo also secured an FA Cup but the 46-year-old was sacked the following season.
