Given a favourable draw - which for Arsenal, Manchester United and Chelsea probably means avoiding the likes of PSG, Dortmund or Napoli this time around - it is possible for pot one teams to maintain a coefficient high enough to keep them there solely through good results against lower-ranked teams in their group.
Arsenal are a prime example of this sort of 'flat-track bully'.
In the past five seasons, the average rankings of the other teams in the Gunners' group has been 55, and they have not even had any dark horses like Dortmund were last year to deal with - in fact, the furthest any of their group rivals has got in that time is the quarter-finals. That happened three times, and the teams involved (Marseille, Shakhtar Donetsk and Porto) lost by a 13-3 aggregate scoreline.
The Gunners, who have had an average ranking of five in the same period, still only topped their group twice, but qualified for the last 16 on each occasion, for which they received five bonus coefficient points to go with the ones they picked up for their results.
So they got an easier group because of their seeding, and consequently qualified from it to get bonus points that gave them an extremely good chance of the same thing happening again the following season. Which it did.
