In beating United, they became the first team to win 14 consecutive Premier League games in a single season, with Arsenal’s achievement spanning the 2001-02 and 2002-03 campaigns.
However, City now hold the record outright after goals from David Silva, who scored in each half, Kevin De Bruyne and Sergio Aguero comfortably secured the points at the Liberty Stadium.

City have been near-invincible this season and have not dropped points in the league since being held to a 1-1 draw at home by Everton in their second game of the campaign in August.
Guardiola’s men appear to be nailed on to replace Chelsea, who won 13 games in a row last season, as Premier League champions given they hold an 11-point lead over nearest pursuers United.
In sweeping all before them in the league, City have rattled in 52 goals in their 17 games, and have conceded just 11.
