Portugal's stuttering form continued as a goalless draw at home to 10-man Albania on Wednesday left them in third place in Group One.
The Portuguese have now gone three World Cup qualifiers without a win and lie two points behind joint group leaders Denmark - who have a game in hand - and Hungary. Perhaps more worryingly for coach Carlos Queiroz, his side, which on paper boast a wealth of attacking talent, have not scored in their last two games.
Albania played the entire second half with a man less after substitute Admir Teli was sent off in the 42nd minute - just 18 minutes after coming off the bench. But they battled for a draw which leaves them level on five points with Portugal and Sweden.
In the other game in the group, a goal midway through the first half from Sandor Torghelle gave Hungary a 1-0 over Malta.
The decisive blow came in the 23rd minute when a cross from the right by Roland Juhasz was headed home by Torghelle to give Hungary their second win in a row.
Malta are still looking for their first point and goal of the campaign after a fourth consecutive defeat.
Two goals from Wayne Rooney helped England continue their flying start in World Cup Qualifying Group Six with a 3-1 win over Belarus on Wednesday.

England needed only five minutes of the second half though to regain the advantage through Rooney, and the Manchester United striker found the target again with 15 minutes remaining to kill off the match.

Georgia and Bulgaria are still winless after playing out a goalless draw which leaves both teams struggling to qualify for the finals in South Africa. Bulgaria were considered favourites for the tie having held world champions Italy to a draw at the weekend, but it was the hosts who played the better of the two countries and deserved all three points rather than one which did neither nation any favours.

The duo now head the group on nine points, with Austria, France and Romania - the latter two having a game in hand - all on four.
In Kaunas Danilevicius scored his third goal of qualifying as Lithuania squeaked past their visitors.
