From the start of November until the end of January, City scored 81 goals in 23 games. That's just over 3.5 per game! In February, City have scored 3 goals in 5 games, less than a goal a game. The goals have dried up recently, leading to just 2 wins and a draw from the 5 games. How worrying is this? What has caused this? There are several possible reasons.
- Regression to the mean - for 3 months City scored at a frankly ridiculous rate, at some point this rate was bound to drop. Form fluctuates up and down, and so this could be just a blip. We were above average for 3 months and then below for a month. If this is the case then the goals should return soon.
- Opponents have worked us out - we're now well into the second half of the season. Other teams have had plenty of time to study how we play, to look at what other teams have done against us that has/hasn't worked, and so to adjust their tactics against us. For example, the game against Arsenal showed what happens when you try and meet fire with fire, but Crystal Palace showed what is possible by being defensive. Arsenal were destroyed, and Palace could easily have got something out of the game - their tactics very nearly worked. If teams are concentrating on stopping us scoring and adapt their tactics, this will make it harder to score. The key to this is that City need to adapt their own tactics. The FA Cup game against Chelsea could be a sign that we are willing to do this.
- Injuries to key players - it's not a coincidence that our early struggles in defense coincided with a series of injuries at centre back. We've recently been missing some key players (e.g. Aguero, Nasri) who would have given us added firepower. No side, however deep their squad, is as good if multiple key players are out injured. This is especially true if the injuries are concentrated in one position. Early in the season injuries to centre backs meant Javi Garcia played out of position there, recently multiple injuries in midfield meant Demichelis played there. This usually means the team's performance will drop.
- Loss of form of key players - the early season defensive struggles were, in part, due to Joe Harts poor form. Recently Negredo's form, for example, has been poor. This happens as form can fluctuate and usually a player can be rested and given a bit of time to get his form back. The injury to Aguero, however, has meant this can't happen.
The most likely explanation is a combination of the above. Of the above, 3 and 4 do happen. The problem is that they have both happened in the same area of the team. Usually they will be scattered throughout the squad and so the depth of the squad can be used to cover for this. Point 1 above should come to an end, the goalscoring should fluctuate back up. The reason to worry would be point 2. If teams are finding a way to stop us then we need to make adjustments of our own. Can we do that? The rest of the season will hinge on how big a factor this is and if we can find an answer.
