Totally agree mate. One of the problems we've had this season is that with the 4231 shape we play, whoever is in the number 10 position has to completely run the game for us. The ball always goes through them, they dictate the way we play, knit the team together. It's no coincidence that when Silva was on his best form in the first 5 games, we got the best performances as a team.
When Silva's form dropped, so did that of the team. When DeBruyne has played there we've looked sensational on the break at times, his early balls and directness can be devastating for teams that are allowing space in behind them. The problem comes when a team is sat deep allowing no space behind, DeBruyne's attributes become completely redundant. I know he played the majority of the game in Madrid from wide, but the emphasis was still on him to get on the ball and dictate play. He wasn't interested.
Although he's had a poor season, we missed Silva in the Madrid game more than any other. There was no one on the pitch interested in getting on the ball, showing feet and looking to get at Madrid. Even at his worst, Silva always takes that responsibility to give an option, get on the ball, dictate play. But against Madrid we had absolutely no one even trying to get on the ball in advanced areas. DeBruyne followed up that performance against Arsenal, he hid, went missing.
I've seen many people claiming DeBruyne will be our "playmaker" for the next 5 years. Against footballing teams that leave space in behind, he will be near enough unstoppable. Be against tough, resilient teams who sit back? I just don't see it.
