#3 Chelsea (2004-05 Premier League winners)
Jose Mourinho, one of the most exciting young coaches in world football, arrived in the Premier League when he was appointed as the manager of Chelsea.
Owner Roman Abramovich was intent on making Chelsea one of the biggest clubs in the world and was not afraid of splashing the cash to do so. Chelsea signed Paulo Ferreira, Petr Cech, Didier Drogba, Arjen Robben and Ricardo Carvalho in 2004 to become a force to be reckoned with.
Mourinho's Chelsea announced themselves in emphatic fashion. They won their first league title in 50 years and were defensively well constructed. They registered the most away wins (15), most clean sheets (25) and the fewest goals conceded in a Premier League season (15), among other records.
Chelsea would go on to win two more Premier League titles under Jose Mourinho as the Blues announced themselves as the new powerhouse in English football.
#2 Manchester City (2017-18 Premier League winners)
Nicknamed 'The Centurions', Pep Guardiola's Manchester City became the first Premier League team to notch up a whopping 100 points in a season.
That was one of many records Manchester City set during their victorious 2017-18 Premier League campaign. There were doubts about whether Guardiola's philosophy would yield him results in England, but City's exploits in the 2017-18 season silenced all his critics.
Manchester City were utterly ruthless and efficient that season. They had spent heavily that summer, signing the likes of Kyle Walker, Benjamin Mendy, Bernardo Silva, Ederson Moraes and Aymeric Laporte. All these players proved to be vital acquisitions.
Apart from their Premier League success, Manchester City also triumphed in the League Cup that campaign. Sergio Aguero was the top goalscorer for the team, with 21 league goals, while Raheem Sterling, Gabriel Jesus, Leroy Sane and Kevin De Bruyne also enjoyed fabulous campaigns.
#1 Arsenal (2003-04 Premier League winners)
Arsenal went unbeaten during the 2003-04 Premier League season, earning the moniker 'The Invincibles'.
The Gunners signed goalkeeper Jens Lehmann from Borussia Dortmund that summer and the German would prove to be a shrewd acquisition. Arsenal won 26 of their 38 league games, drawing the other 12.
French striker Thierry Henry, regarded as one of the greatest players to have played in the Premier League, scored 30 league goals and won the PFA Players' Player of the Year award. Lehmann, Ashley Cole, Robert Pires, Kolo Toure and Lauren were consistent starters throughout the season for Arsenal.
Arsenal did not fare as well in other competitions that campaign, though. They lost in the semi-final in the FA Cup and League Cup and were knocked out of the Champions League in the quarter-final. However, in the Premier League, Arsene Wenger's men scripted history, as they became the first team to go unbeaten in a season.
