In advance and on a cruise at the break thanks to the group goal of Jamie Vardy, four calamitous moments in just over 60 seconds in the second period sent City to defeat.
First, Kasper Schmeichel kicked a goal on his own man to put Bournemouth to the goal. Second, Wilfred Ndidi triggered Callum Wilson, allowing Stanislas Junior to convert.
Third, Jonny Evans misread a header and Dominic Solanke escaped to score a second for the hosts. Fourth, Caglar Soyuncu responded immaterially and got a red card.
If City fails to finish in the Champions League places and a win for Manchester United on Monday night brings them back to fifth, then those four moments will be remembered.
City will hold the hope that the Sports Arbitral Tribunal will rule against Manchester City on Monday morning and that fifth place will become a place in the Champions League. But if this is not the case and that City misses a place at the top of Europe, they can only blame themselves.
