Arsenal and Poland goalkeeper Wojciech Szczesny has warned against complacency when his side host Scotland on Tuesday.
Following Szczesny told BBC Scotland: "Of course it will give us a lot of confidence.
"But there is a danger of complacency because you want to enjoy your win."
The 24-year-old says the should serve as a warning about the threat Gordon Strachan's team can pose.
Szczesny was beaten by a Scott Brown shot from the edge of the box in that win for Scotland in the spring and he was in goal for Poland in Saturday evening's 2-0 triumph over Joachim Low's Germany in Euro 2016 qualifying.

The three points lift Poland, ranked 70th in the Fifa world list prior to that historic victory, to the top of Group D.
Having begun their campaign with a 7-0 rout in Gibraltar last month, Poland now have six points from their opening two matches and are ahead of the Republic of Ireland on goal difference.
"We have come up against the world champions and we managed to get a great result," said Szczesny, after Arkadiusz Milik's header and a late Sebastian Mila strike secured the win.
"We performed brilliantly. We were told to let Germany come in to our half and we were confident in our defending.
"We tried to break them up at every opportunity and we did that very well."
Szczesny says he does not yet know what the game plan will be for the match against Scotland in the Stadion Narodowy, but he is focused on preparing well.
Meanwhile, Scotland put in a solid performance to beat Georgia 1-0 at Ibrox on Saturday.
"Now we have to get everyone on board for the game on Tuesday," he said.
"We'll be confident against Scotland but they are a great side. They beat us here, so we know we're going to have to be at our very best to beat them.
"There's a sense of revenge. We don't like to lose games, especially at home. They played very well here, it was a fair result so we will be looking forward to payback."
Asked about Scotland's recent improvement - they are now 29th in the Fifa world rankings - the Arsenal keeper said: "I think they've come up about 40 positions in the Fifa rankings so that shows you they have made a big step forward.
"They have fantastic, experienced players who play regularly in the Premiership. We realise they will be a very tough game."
