St Johnstone briefly led against Galatasaray at 10 before securing a 1-1 Europa League draw in Istanbul.
Saints captain Jason Kerr silenced Basaksehir Fatih Terim stadium with a penalty in the 58th minute after the home keeper was sent off.
But the lead only lasted two minutes before Sacha Boey capitalized on a defensive error in judgment to equalize.
The Saints couldn’t really make the most of their men’s advantage, but Stevie May had a clear shot from the line and Callum Davidson’s side put on a huge night in Perth next Thursday, with a spot for them. play-offs up for grabs.
The Scottish Double Cup winners survived an early attack at the stadium which is named after the Galatasaray manager but is owned by one of their Istanbul rivals, Basaksehir, with their own house under renovation.
Mostafa Mohamed missed a goalkeeper three minutes later when he recovered from six yards and Kerem Akturkoglu hit the post from 15 yards five minutes later.
Zander Clark made a great save in the follow-up, but the flag was raised, but the Saints goalkeeper was quickly back in action to stop a header from Brazilian defender Marcao.
The Saints settled in and Murray Davidson and David Wotherspoon were able to save their efforts, the latter having a particularly good chance of shooting straight at the goalie.
The hosts also started the second half strong and Berkan Kutlu sent a free header over the bar at eight meters.
The Saints received a gift when a bad back pass put goalkeeper Fernando Muslera in trouble.
The Galatasaray skipper made the inexplicable decision to kneel under pressure from Chris Kane and the ball bounced off his leg and into the path of the Saints forward. Muslera pulled Kane down and received a straight red card.
After a long delay, center-back Kerr kept his cool to shoot into the corner of the net in front of substitute goalkeeper Berk Balaban.
The Saints could not profit from their lead for long. Manchester United left-back on loan Reece Devine tried to cut a pass to French right-back Boey but missed the ball, and the debutant – who had been linked with Celtic this summer – took advantage, drilling an angle drive in the far corner.
Balaban almost offered the Saints another goal, losing the ball to May near the corner flag, but the substitute’s effort at a difficult angle was wiped from the line.
The 10 men finished strong. Jamie McCart produced a superb header block on Marcao’s volley before Clark made a superb Christian Luyindama header save to secure a famous result for the Perth men.
St Johnstone will face Motherwell at McDiarmid Park in the Scottish Premiership on Sunday at 3pm, before facing Galatasaray at home in the second leg on Thursday at 7pm.
