Bayern Munich's midfield is very strong. They have several talented midfielders in their squad. And every midfielder is very helpful and friendly. So Harry Kane gets a lot of help from the midfielders.
Yeah you are right because with how strong Bayern Munich midfielders is it will be very difficult for other clubs to penetrate and also I agree that is actually one of the reasons why Harry Kane is performing the way does because irrespective of how strong and performance a player is if there is no assistance from the other players he will find it very difficult to perform, so actually Bayern Munich has been the source of Harry Kane performance because they are actually given him all he needed to score. Although during his time on Tottenham Hotspur he did not have such assistant he has on the Bayern Munich midfielders that's why his performance is more better now than when he was still on Tottenham Hotspur.
The midfield is the lifeblood of a team's game, they have a huge impact, if the midfield doesn't play well, then the impact will be felt in all positions. Even if a club's defense and attack are good, if it is not supported by a strong midfield it can fall apart.
Especially now that the style is more about foot-to-foot play, the distance between players will be an important factor. The midfield is like a bridge between the back line and the front line, if they fail to be the link between those positions, then I can say they will fail.
They also need to have quick rotation, I mean when they are attacked and then counter-attacked then the rotation has to be quick, and vice versa. Right now a lot of the midfielders are also getting a lot of attention, because their absence is very noticeable for the squad that is playing.
