The Oil Derby

I am not going to write anything against Pep ( The Tactical God), because  the game was even if City had taken those chances.   

Key tactical things, that I have noticed last night:

City's press was excellent in the opening minutes & for most of the first half. City pressed in a sort of 3-3-3-1.

This allowed Mahrez and Grealish to press the PSG central defenders, while KdB, Silva and Rodri marked the PSG midfielders. Sterling led the direction of the pressing. 

This forced Donnarumma to make long passes into space for the PSG fullbacks. 

If City saw that a fullback was the target for a pass during the PSG build up, the ball-sided midfielder, Rodri or Silva, would leave their designated man-marker and press the fullback in possession.

PSG mostly used the right side of the pitch when attacking.

Hakimi would stay wide to receive a pass and would look for Messi, Verratti or Herrera. Grealish would screen Herrera, but Cancelo was too keen to press Messi, creating space between him and Laporte for Herrera to use. 

If PSG had no forward or neutral passing options, they were always comfortable going backwards to Marquinhos.

To beat City's press, Verratti could be seen dropping into the PSG backline to form a back three. 

This forced City to commit another player forward to the press, allowing PSG to move the ball forward easier. 

City's build up plan was catered to a more relaxed PSG press compared to their own. 

Ederson in would stay between the CBs. Walker would move into a more advanced position along the touchline, while Cancelo tucked inside to make up a deep three man midfield. 

KdB was often marked or at least close enough to a PSG player to be pressed.

However, KdB was rarely the target during City's build up phase. The objective for City was to get the ball up by any means necessary.

City's attacking structure resembled a 3-2-5 at times. 

Mahrez remained wide on the right while City progressed up the left. Cancelo, Grealish and KdB would combine to isolate Messi & Hakimi.

Once the PSG block was moved to the left, City would switch the ball to the right. 

The plan worked, but the execution was flawed. Mahrez struggled to beat Mendes, leading to wasted possession. 

Jesus would have been a better option for this role as he has been successful on the right hand side for City in the Premier League this season.

If City kept their attack going down the left, instead of switching, it resembled a 3-3-4.

Cancelo and Grealish would remain wide on the touchline, dragging Messi and Hakimi out of position. 

This created space in between the midfield and defensive lines for Silva to move into. 

This was City's game to lose. In all phases of play, City dominated. 

It's hard to say if any one player is to blame for this loss. PSG took advantage of the chances they created while City did not. It's that simple.
