KDB played as the number 10 at Wolfsburg. He scored and assisted from that position. That is why we bought him. Now I am not saying he is better than Silva. What I am saying is he is playing out of position for us. I believe we would see an improvement if we played him in the number 10 position.
There are different type of playmakers as there are different type of wingers, forwards etc
He hasn't done the job of playmaker for us because he is not being played as such. This doesn't equate to not being a playmaker.
Playmakers dictate play, usually from the middle. You're quite right that Silva over the years has started wide and drifted inside.
I appreciate De Bruyne often played centrally for Wolfsburg and did brilliantly. The difference being Wolfsburg were a top 6 side, teams didn't park the bus against them. Most of De Bruyne's good work was exploiting space in behind teams, either hitting an early, direct ball or running in to the space behind.
The difference playing for City is we're the best team in the league. Most teams park the bus, sit back and leave no space in behind. That negates a lot of De Bruyne's game. It requires more acute technique, intelligence and subtlety. De Bruyne is currently not at or anywhere near Silva's league on those things.
De Bruyne has tried to play as a playmaker for us in the first 25 minutes against Newcastle, and in the 7 weeks Silva was out. He was dreadful trying to play that role, it's not his game.
Playing as a playmaker for a top 6 Bubdesliga side who play on the counter is quite different from being a playmaker for the best team in the Premier League who dominate possession. By the same token, Silva wouldn't have been suited in doing the job De Bruyne did for Wolfsburg, he's got a different set of skills.
I've seen De Bruyne's biggest fan on here say "well he's got the best goals and assists record, and the stats are the most important thing". Unfortunately if you look at the game only through those parameters you don't really understand the game, and probably never will.
For me the most important thing is for the team to play well. If they do, results will come. The team has played best without De Bruyne in the side. Maybe it's coincidence, or maybe he's upset the balance of the side? For those who struggle with intricacies of football and only understand stats, check the stats from the first 5 games of the season before De Bruyne signed.
