Chris Coleman's side are now above the Netherlands, who have dropped down to 12th.

Argentina remain in the number one spot, with Belgium back up to second and Germany in third.
Wales beat Belgium in a Euro 2016 qualifier in June, which resulted in a leap of 12 places in last month's rankings to reach the top 10 for the first time since they were introduced in 1993.
Cyprus will be Wales' next opponents on 3 September, with a home game against Israel to follow three days later.
Coleman's side are three points clear of Belgium with four games left in the qualifying campaign.
