Roma midfielder Radja Nainggolan is still missing from the Belgium squad announced by coach Roberto Martinez on Friday for World Cup qualifiers against Bosnia-Herzegovina and Cyprus next month.

The out-of-favour Nainggolan was also left out of Martinez's last squad for September qualifiers.

Martinez explained his decision was for "tactical reasons" and because he wanted to "work with continuity".

Belgium, who have already qualified for Russia 2018, end their qualifying campaign against Bosnia on October 7 and then Cyprus three days later.
