The Reds have conceded at a rate of almost two goals per game in the 2016-17 A-League and copped three in their ACL opener
Adelaide United will need to tighten their defence if they are to get anything from their AFC Champions League (ACL) clash against Jiangsu Suning in China.
Apart from a 1-0 triumph over Newcastle Jets in the A-League on February 17, the Reds have conceded at least two goals per game in their last seven matches in all competitions.
Despite an impressive performance from 19-year-old goalkeeper Daniel Margush on the weekend, Adelaide still lost 2-1 away to Melbourne Victory, while they were defeated 3-0 at home by Gamba Osaka in their ACL opener last week.
