"I thought our discipline, defensively, throughout the game was very good", Palace manager Roy Hodgson said.
As the clock ticked on, Pep Guardiola's side continued to turn the screw, with the Palace shot stopper forced into two smart saves courtesy of an Aguero header and a venomous Leroy Sane half-volley from close range within five minutes of one another to keep his side level. I don't know what happen with him in that last action.
"But my feeling now is Alexis is an Arsenal player".
Palace became only the second team to take points off City in the league this season, halting their winning streak at 18 games, and travel to 13th-placed Southampton on Tuesday but face a tough task with a stretched squad.
City attempted to sign Sanchez, whose contract expires at the season's end and who Guardiola once signed for Barcelona, during the summer transfer window.
After the break, City were finally able to produce a more cohesive display to that of their fractured first 45, which saw several misplaced passes and a couple of on-field spats, and the visitors nearly found the breakthrough 10 minutes in as Ilkay Gundogan whipped his attempt from range just past Hennessey's right-hand upright. "I try to win the game, and especially focus on Watford". Maybe Arsene (Wenger) is anxious about that but I tell him many times that 2004 run is for him.

He said terrorism and violence were so widespread there that his family had to leave their ancestral land and flee. "As a child, Anjum never gave up hope".
"I don't know (what's going to happen) but he's a player of Arsenal and I think he is going to stay there", he said. "Today is completely different to 2004".
This was City's first away goalless draw in the Premier League since March 2016 against Norwich City, ending a run of 34 matches in which at least one goal was scored.
And while Guardiola says that De Bruyne may have been "lucky", the early indications are less positive on Jesus. "In two days we have another game after that we have meetings".
Guardiola's team have already passed many tests this season, but it is now that their endurance will be questioned.
It is all "ifs" right now, but the chasing pack did not even have those to cling to before the Crystal Palace game.
Yet after being so impressive for so long, the draw at Crystal Palace offered proof that City can be stopped. I admire the physicality of the Premier League but the referee has to protect the players - that's all I ask.
