It is a 1-4-2-3-1 system that combines the security of playing with a double pivot in the center of the field, to then give prominence to the line of 3 attacking midfielders.
This line of 3 midfielders and the mobility of the striker, will depend on us not to be a little lame in attack. It is also important to consider the height of the fullbacks, which can give us more or less depth.
You can see this system on toplidercoach.com, mainly through Nagelsmann's exercises, which he is constantly developing at Bayern Munich.
