Does attack or defence win Premier League titles?

Friday 25 August 2017 12:53, UK
Sir Alex Ferguson once claimed "attack wins you games, defence wins you titles" - but is that true?
Liverpool host Arsenal live on Sky Sports this Sunday and both sides have displayed potent attacks in the early stages of the season - but they have also shown defensive frailties.
So can teams with weaknesses at the back win the title? Yes they can.
Unsurprisingly, Premier League champions have typically been strong at both ends - but ultimately they've been better in attack.
Since 1995/96, the average champions have ranked 1.45 out of 20 teams for their goals scored, compared to an average rank of 2.41 for goals conceded.
In total, 14 out of 22 champions have had the strongest attack during the respective season - but only nine have had the best defence.
In fact, Sir Alex was the master for winning titles with an inferior defence - mitigated with a league-topping attack.
Manchester United only had the seventh best defence when they won the title in 1996/97, shipping 44 goals - Blackburn conceded fewer and finished in 13th place.
And Fergie continued in the same vein, having only the fourth best defence in 1998/99, the sixth best in 1999/00 and fifth best in 2012/13.
In each of those title-winning seasons, United scored more goals than any other team.
PERFECT CHAMPIONS?
There have only ever been five 'perfect champions' over the last 22 years - having scored more goals and conceded fewer than any other team.
Manchester City's class of 2011/12 were superior at both ends, as were Manchester United in 2007/08 and 2000/01, Chelsea during 2005/06 and Arsenal in 2003/04.
LUCKY CHAMPIONS?
If the final table was based on the average rank of each club's attack and defence, six of the previous 22 champions wouldn't have won the league.
Manchester United would have finished fourth in 1996/97, behind would-be champions Arsenal, Liverpool and Newcastle.
But Arsenal would have had their 1997/98 title stripped, with United lifting the trophy instead - before the Gunners topped United during the 1999/00 campaign.
Again, United would have lost another title in Fergie's final season at the helm during 2012/13, finishing third behind champions Chelsea and Arsenal.
Most recently, Tottenham would have won the Premier League for the last two seasons - stripping Leicester's fairy-tale adventure and Antonio Conte's title-winning Premier League season at Stamford Bridge in the process.
GOALS ON THE RISE (IN MODERN TIMES)
The average goals per game in the Premier League has increased marginally year on year for three consecutive seasons.
However, that 2.8 goals per game average in recent top-flight football is dwarfed by the 4.7 goals per game recorded in 1889/90.
Aston Villa scored a remarkable 128 goals in 1930/31 - more than any other top-flight side in the history of English football.
Despite their record goal haul, Villa still only finished the season as runners-up, behind Arsenal - who had scored 127 goals.
Arsenal will be hoping to rekindle that kind of goal-scoring form when they travel to Liverpool on Sunday, while Jurgen Klopp will be looking to inflict a second successive defeat upon their visitors.
