During this run, City broke the records for most consecutive wins by a top flight English team in all competitions (21), the most consecutive league wins by a top flight team from the start of a calendar year (13) and equalled their club record for 28 games unbeaten in all competitions.
[6] On 25 April, the Blues defeated Tottenham to win their record-equalling fourth consecutive, and eighth overall, League Cup title.
[7] On 4 May, City reached the Champions League final for the first time in their history as they defeated Paris Saint-Germain 4–1 on aggregate in the semi-finals.
[8] On 11 May, the Citizens were officially confirmed as Premier League champions for the third time in four seasons following a 1–2 home defeat of second-placed Manchester United at the hands of Leicester City.
On 29 May, City were defeated 1–0 by Chelsea in the Champions League final, ending their hopes of winning a treble and clinching the first European trophy since 1970.
Rúben Dias, Phil Foden, Kevin De Bruyne and Pep Guardiola were amongst the City representatives recognised in the various end of season awards.
City had invested heavily in their central defence during the summer with the purchases of Rúben Dias from Benfica and Nathan Aké from Bournemouth.
The transfers were designed to improve the team's perceived weakness in the defensive area since Vincent Kompany had left City at the end of the 2018–19 season.
Some initially inconsistent league results left City in the bottom half of the table when they were defeated 2–0 by Tottenham Hotspur on 21 November (albeit with a game in hand over many of the clubs above them).
City were undefeated in cup competitions by the end of 2020, reaching the semi-finals of the Carabao Cup for the fourth consecutive year and, more importantly, the knockout stage of the UEFA Champions League for the eighth consecutive season, with their highest ever group stage points total (16 points).
In February and March, City maintained their form to extend their winning run in all competitions to 21 games, a new record for a top flight side in English football.
[16] On 16 March, City defeated Borussia Mönchengladbach 2–0 (4–0 on aggregate) and advanced to the Champions League quarter-finals for the fourth year in a row.
[17] On 20 March, the Blues scored two late goals to beat Everton on the road and advance to the FA Cup semi-finals for the third consecutive year.
All attendees would have to consent to mandatory COVID-19 testing before and after the event, travel only by car or on specially chartered trains and coaches from Manchester and provide contact data for track and trace purposes.
[25][26] The following day, 18 April, it was announced that City had joined the proposed European Super League as one of its twelve founder members together with the five other "Big Six" English football clubs.
[27] However, the announcement led to widespread condemnation from The Football Association, the Premier League, UEFA and FIFA, as well as from the UK's Conservative government and Prime Minister Boris Johnson.
This victory was the club's fourth consecutive EFL Cup title and their eighth overall, matching the records held by Liverpool.
[32] On 4 May, City reached their first ever European Cup / Champions League final by defeating Paris Saint Germain 2–0 (4–1 on aggregate) in the semi-finals.
The Blues previously failed to complete their league victory on the previous weekend, when they fielded a team with eight changes from the second leg of the Champions League semi-finals and were beaten 1–2 at home by Chelsea, but second-placed Manchester United's 1–2 home defeat to Leicester City three days later left City ten points ahead with only three games of the season left to play.
Kevin De Bruyne was brutally injured by Antonio Rüdiger in the second half, and N'Golo Kanté's brilliant performance limited City's attacking options.
[35] Still, City's European breakthrough signified their most successful season to date and Pep Guardiola showed his pride in the runners-up medal.
Manchester City lodged a request with the Premier League to rearrange the fixture following an increase in positive SARS-CoV-2 test results received by the club earlier the same day, on top of four positive cases reported on Christmas Day for two non-playing staff, Kyle Walker and Gabriel Jesus.
