For 40 odd minutes, Claudio Bravo's initiation into English football appeared to be going swimmingly.
Now deep into the second half, however, the Manchester City goalkeeper - recently signed by Pep Guardiola to replace Joe Hart - is teetering on the brink of a howler.
First, almost on the stroke of half-time, the ex-Barcelona 'keeper failed to collect a cross and allowed Zlatan Ibrahimovic to pounce to cut the deficit to 2-1. Now, mid-way through the second-half, many believe Bravo is lucky to still be on the pitch after a full-blooded collision with Wayne Rooney.
Supposedly brought in because of his superior ability with the ball at his feet, it was Bravo's over-confidence in his touch that put him in trouble in the second half.
Trying to create space for himself, he tried to avoid one United player but only put himself in the path of Wayne Rooney. Trying to win the ball, Bravo's studs up challenge was on the edge of legality...
Reacting to the replay on Sky Sports, Gary Neville immediately claimed the 'keeper was lucky to have escaped a red card, and a lot of people watching as fans were inclined to agree.
In the end, Bravo escaped without even a yellow card and remains on the pitch as the game goes on.
With United building up a head of steam, City fans will be hoping he can regain his composure to help see out what would be a famous win.
