Arsenal head into the World Cup break top the Premier League and their scintillating attack has been key to that. The signing of Gabriel Jesus has been transformational, while the continuing upward trajectories of Gabriel Martinelli, Bukayo Saka and Martin Odegaard have gained plenty of attention.
What has flown slightly under the radar though, is the improvement in the Gunners' defence.
With 14 games played they have the Premier League's joint-meanest defence with just 11 goals conceded so far. This is nearly half the number they had let in at the same stage last season (20). So what exactly has changed?
