Sanchez will only make City stronger and more formidable, but Guardiola has already highlighted the physical demands of playing up to eight games in January, so even the addition of the Arsenal forward may not be enough to stave off a hard month. He made his way to the dressing room in tears, consoled by City's medical staff. The referee has to follow the rules and protect the players. "It's OK. But there are limits".
City midfielder Kevin De Bruyne was also injured against Palace. Guardiola said Sunday it was too soon to know how serious De Bruyne's injury was, but he estimated that Jesus most likely would be sidelined "more than a month".
Asked whether the injuries would prompt City to move for Sanchez, Guardiola said: "In internal meetings, we are going to decide what is the best but my feeling now (is) Alexis is an Arsenal player and he will be".
They regardless remain undefeated, in first place, and 14 points above closest challengers Chelsea, but Guardiola played down their chances of emulating Arsenal in 2004, when the Gunners went the entire league season without defeat.
But the inevitable focus on the consequences of Sunday's match for City could not diminish the achievement for its opponent.
However, maybe more troubling for Pep Guardiola was witnessing star Kevin De Bruyne stretchered off in injury time with his leg in a brace after a horrifically mistimed challenge from Jason Puncheon as the visitors looked to break from the saved spot kick.
In a game of such mismatched teams, this draw should feel like a win for Palace.
"I am not thinking to be unbeaten", said Guardiola afterwards.
And it would have been even better for Palace had Luka Milivojevic converted a stoppage-time penalty after Raheem Sterling was adjudged to have fouled Zaha in the area.
Guardiola also spoke about the game that ended his record with City and the performance of his goalkeeper, Ederson.
Guardiola defended his side's rare slip-up, insisting dropping points was always going to happen. In the 2003-04 season, Arsenal became the only club to get through an entire 38-game Premier League campaign without a defeat.
