These two sides are amidst very different runs of form. Scotland's form has collapsed in the last year, with Steve Clarke's side registering just one win in their last 13 games - a 2-0 win over Gibraltar.
Portugal, by contrast, have won five of their last seven games and have lost just one of their last 11 games in Portugal.
Portugal have won four of their last five head-to-head meetings with Scotland and haven't lost to them since 1980, and it's very hard to see that run turning around here. Portugal 3-0 Scotland.
