Tuesday's 1-0 win was Arsenal's ninth clean sheet in 14 matches in Europe – they have only conceded two goals in six knockout games – and their 30th overall this season.
They have allowed their opponents an expected goals (xG) of just 0.84 per game, and seven of the past 13 Champions League winners conceded fewer than 1.0 xG per game on average during their successful campaigns. In comparison, PSG's average xGA – expected goals against – in Europe this season is 1.38.
There is no denying it will take a monumental Arsenal effort against PSG if they are to lift the Champions League trophy for the first time.
Reigning champions PSG have netted 44 goals in just 16 matches in Europe – with six of them coming in the semi-final against Bayern, who themselves scored 43.
Only Barcelona, who scored 45 times in 16 matches in 1999-00, have more in a single season.
One only has to look at last season's final to appreciate how quickly Luis Enrique's PSG side can blow teams away. Inter Milan conceded just once in their eight league-phase matches, but shipped five in one of the most one-sided European finals.
The Gunners defeated PSG 2-0 at Emirates Stadium in the league phase of last season's competition, but the French side prevailed in the semi-finals, running out 3-1 aggregate winners on their way to clinching their maiden title.
Arsenal will now hope to avenge that heartbreak in perfect fashion in Hungary at Puskas Arena.
"The final will be fascinating," former Manchester United midfielder Owen Hargreaves said. “PSG will be more attacking than they were against Bayern, but this is a different Arsenal now.
"They went through a little blip the last few weeks. They believe now. They have a chance. They just have to believe."
