Two unbeaten giants fell in yesterday’s UEFA Champions League fixtures. Both Bayern Munich and Inter Milan suffered their first defeats of the campaign, leaving just one club with a flawless record — the impressive Arsenal under Mikel Arteta.

The secret behind Arsenal’s near-perfect run has been its rock-solid defensive structure. The Gunners have conceded only one goal so far, a testament to their discipline and organisation. Their attacking output — 14 goals in five matches — isn’t the highest in the tournament, but the balance and control displayed by Arteta’s side have made them one of the toughest teams to break down in Europe.

At the opposite end of the standings sits the season’s biggest disappointment: Ajax. The Dutch giants, four-time winners of the Champions League, have yet to earn a single point. Their illustrious history feels very distant now, as the Amsterdam club finds itself anchored to the bottom of the table in a campaign that has offered little hope and even fewer positives.
