Two more sections reach their gripping conclusions on Tuesday, 24 June.
In Group C, FC Bayern München are already through and will top the table if they avoid defeat against SL Benfica. The Lisbon side, for their part, will make sure of progressing with a point and could even qualify if they lose - depending on the result when CA Boca Juniors take on Auckland City FC.
Boca need to beat the New Zealanders, hope Benfica lose to Bayern and finish above the Portuguese side on goal difference. Other tiebreakers may also come into play.
In Group D, Chelsea FC take on Espérance knowing that only a defeat can deny them a place in the Round of 16. Only a win will do for the Tunisians. CR Flamengo, who are already assured of qualifying as section winners, will be looking to maintain their 100 per cent record against already-out LAFC.
