I don't think the alarm bells will be ringing too loudly at Manchester City despite them losing three consecutive games.
There are two very obvious reasons for me that stand out. One is their most creative player, and arguably their best, Kevin De Bruyne, has not been fit. Secondly, and not far behind in terms of value to the team, has been Rodri's absence.
If you didn't know the scoreline from their Champions League defeat to Sporting Lisbon, you would evaluate the statistics after the game and say City should have won.
