Sheikh Mansour has promised that Manchester City will continue searching for trophies after watching his club lift the European Cup in Istanbul.
City's owner was in attendance for a game for only the second time since buying the club in 2008, and for the first time since 2010. He didn't see a classic Champions League final, but City edged a tight game thanks to Rodri's goal and completed a historic treble.
After sealing a fifth Premier League in six years, City added the FA Cup to their collection last week and followed it up with a first ever European Cup in Istanbul on Saturday - with Sheikh Mansour watching on.
And the owner took to Twitter to send a public congratulations to City - with a message that will put the rest of Europe on alert.

"My congratulations and gratitude to our loyal Manchester City fans, and everyone at the Club, including management, technical staff and players," he wrote, adding: "We will continue to define and celebrate our success together."
Pep Guardiola spoke of going again in search of more trophies after finally sealing a European Cup with City, saying he hoped that he would be able to help City defend their title in next season's Champions League.
"We will start from zero next season," said the manager.
Sheikh Mansour watched the Champions League final sat alongside chairman Khaldoon Al Mubarak, wearing a City scarf, with fans singing his name at various points of the final. City have now won every trophy they have competed for under his ownership, and will try to add the UEFA Super Cup and FIFA Club World Cup to their cabinet after winning the Champions League.
