One of the most enthralling Premier League title races of modern time - lit up by some of the biggest and most expensive stars in the division - may have been decided by a man signed on a free from German side Arminia Bielefeld after they had just been relegated from the Bundesliga.
Since arriving at Manchester City in summer 2022, Stefan Ortega has repeatedly shown himself to be a worthy deputy to Ederson. He has looked assured when the Brazil keeper has been injured and thrived in the role of Pep Guardiola's cup goalkeeper - including starting last season's FA Cup final win over Manchester United.
However, Ortega's role in putting City on the verge of an unprecedented fourth title in a row has been a little different.
There have been 15 goalkeeper substitutions in the entire Premier League this season and remarkably four have been him replacing Ederson.
The other four of Ortega's league appearances have been starts in wins over Crystal Palace, Brighton and Aston Villa, as well as the potentially pivotal home draw with Arsenal.
After his stunning cameo against Tottenham on Thursday, we break down the times the 31-year-old has been thrust into the action, and how each time he has risen to the challenge.
