Hamburg have stretched their unbeaten run to four games with a narrow 1-0 victory at Greuther Furth in the Bundesliga.

Heung-Min Son scored the only goal of the match in the 17th minute when he turned home Tolgay Arslan's pass.

The victory was HSV's third in their last four matches and sees them continue their improvement following a disappointing start to the campaign in which they lost their opening three matches.

Furth have now lost for the fourth time in five matches and are firmly rooted to the foot of the Bundesliga table with just four points from seven games.
