Leyton Orient stunned Manchester City with a stunning goal from distance in the FA Cup fourth round.
Jamie Donley, on loan from Tottenham, went for goal for Orient from 40 yards out, with his effort hitting the crossbar before deflecting in off Manchester City goalkeeper Stefan Ortega.
The goal was scored in the 16th minute, with Orient, who play in League One, taking the lead against last season's Premier League champions City.
It was a great moment for 20-year-old Donley, who has made four senior appearances for Tottenham.
There was further frustration for City as new signing Nico Gonzalez had to be substituted after just 22 minutes as he suffered an injury on his debut.
City named the likes of Ruben Dias, Ilkay Gundogan, Savinho, Jack Grealish and Omar Marmoush in the starting lineup against Orient.
The hosts managed to maintain their lead until half time as they looked to pull off an incredible cup shock against City.
Orient have enjoyed an eventful run in the FA Cup this season.
Richie Wellens' side beat Boreham Wood on penalties in the first round before overcoming Oldham Athletic in extra-time in the second round.
They then required penalties to get the better of Derby County.
Donley was making his 31st appearance of his loan spell at Orient as he scored his sixth goal for the club. He has also provided six assists this season.
City went into the game looking to return to winning ways after their 5-1 defeat to Arsenal in the Premier League last weekend.
Following their game against Orient, City will turn their attention to next week's Champions League play-off round clash at home to Real Madrid.
