Over their history, Palace have defeated the champions [whomever they may be, not just City] on seven separate occasions, notching 11 draws and falling to 20 defeats in 19 top-flight seasons.
All things considered, it is a not unimpressive record. The Eagles have collected more wins in 38 league meetings with the country's reigning champion than the last four bottom-placed teams managed against everyone in a whole league campaign.
In recent times, the record is even stronger - Palace have won against the champions in four of their last five seasons, only failing to do so in 2016/17 when they lost and drew with Leicester City.
In the 10 matches over those five seasons, the Eagles have claimed 13 points. It's a fruitless exercise, but applying that points-per-game ratio to a league campaign, earning 13 points from 10 matches it the equivalent of 49 from 38: Palace's highest ever top-flight total.
Outside the league, Palace have only played the title-holders twice, drawing 2-2 with Manchester United in the 1994/95 FA Cup and going on to lose the replay 0-2.
In total, the Eagles have played nine different champions, facing United and Arsenal (eight times each) on the most occasions.
The rest are: Liverpool (six), Leeds United (four), Chelsea (four), Manchester City (four), Derby County (two), Everton (two), Leicester City (two).
There have been 107 goals scored in total.
