``It does not mean a lot if we don't back it up again this week,'' coach Tim Lunnon said as he reflected on his side ending champion South Hobart's 16-game unbeaten streak.

``The way to gain respect is by backing up and that's the challenge to these boys now.''

On a historic afternoon at Darcy Street, Rangers recorded their first ever win over South, taking full advantage of Curran Ferns' 24th minute sending off to win 3-1 through goals by Ryan McCarragher, Shane Brassington and Nick Lanau-Atkinson.

Brassington and fellow Englishman Adam Edwards both struck the crossbar while the former also missed a penalty as Rangers extended their unbeaten start to the season and moved to the top of the table.

Lunnon said much credit should go to central defenders McCarragher and captain Todd Hingston while Harry Thannhauser impressed in central midfield against the competition's benchmark team at the age of just 16.

``I really couldn't fault the boys,'' he said.

``Before the game I said I can't see why we cannot come away with some points. Last year Rangers only got 27 points for the whole season so we need to just keep accumulating points.

``This is something we've never done before and we're very proud of but it's only one game and we're only three games into a 21-game season.''

Lunnon challenged his side to complete another successful sortie to the capital when it plays Tilford Zebras on Friday before hosting Devonport in an FFA cup match at the NTCA Ground on Easter Monday.
