Craig Gordon has urged Scotland's last-gasp heroes to finish the job against Slovenia tomorrow.
Gordon Strachan's men put on yet another late show to grab a crucial 1-0 win over Slovakia on Thursday night.
That Hampden triumph was sealed by visiting skipper Martin Skrtel's last-minute own goal and sets up a do-or-die date with Slovenia.
Victory in Ljubljana will guarantee the Scots second place in Group F and should be enough to book them a World Cup play-off spot.
Scotland have netted seven goals at home during the current qualifying campaign, with five struck inside the final five minutes.
Now Gordon is confident his side's patient approach will see them through their most important test yet.
The Celtic goalkeeper, 34, said: "We've scored a lot of late goals during this campaign and it shows we always go right to the end.
"We've got good fitness levels which ensure we can go right to the end to try and win the game.
"If we keep that spirit together we'll have another good chance going into Sunday's game.
"It will probably be the most important match I've played for Scotland since the Italy game back in 2007.
"It's another chance to progress from a group and this time I hope we can take it.
"At my age there's not going to be too many chances like this left. We've put ourselves in a great position now but we have to go finish the job."
Meanwhile, Charlie Mulgrew has warned Scotland that Slovenia will be no pushovers.
The Blackburn defender believes Srecko Katanec's men will be desperate to scupper Tartan Army hopes at the Stozice Stadium.
"It will be a hard game," said Mulgrew. "International matches are always difficult and this one away from home will be no different."
"But we're going to give it all we can to try and get a result. We've got our fate in our own hands."
