They will swap places with Chile, who are set to drop one to ninth spot despite beating Paraguay 3-2 in a friendly.
Wales stay above England, who will remain 10th despite wins against San Marino and Switzerland.

Northern Ireland are likely to rise from 41st in the rankings, while Scotland will drop from 31st.
