Hey Mate, hopefully i can help you out with the tactic, This one i use on my bayern save and my goal was to recreate bayerns playstyle as close as possible. It was also important to me to use the players in their most played positions from expired season. I will give you some hints on how i created this tactic and what was the idea behind.
Lets start with the Players and their roles & duties:
ST - Lewandowski is a Striker who is not only looking to score goals but also trying to create chances or space for his team mates. Complete Forward is the perfect role for this as it combines goal scoring priority (quite high up the pitch) with a lot of movement (roam form position & move into channels) and creative/supportive aspects (Risky passes & Hold up Ball). I choose Support Duty as he is not the fastest anymore and i dont want him to break through central defense as this area usually is packed with defenders when playing as bayern.
AML/AMR - Coman and Gnabry are very pacy so i both want them to attack the space in front of them. In real Gnabry does cut inside and trys to get into scoring positions whenever lewandowski is pulling defenders away or isnt in a good position yet. So i choose Gnabry to be an IF on Attack. Coman on the other hand will attack wider areas as we dont want pack the middle too much.
AMC - Muller will be a simple, hard working offensive midfielder who does primarily distribute the ball to our wider players. from time to time tho he will join the box and try to score goals. As we are playing with 2x Holding CM's we need him as a support duty to link up play.
CM - As we usually play wide, and with rather aggressive full backs we need a double pivot of holing players in our central midfield to pretend defensive cover. As Thiago is one of the key players in bayerns game, he will be our playmaker and central point of our build up play. With a support duty he will have all the freedom he needs to dictate the game. He will be assisted by a simple defending central midfielder. There were cases last season where Goretzka or Tolisso before he was injured would be more of a threatening player inside the enemies box. If you want to experiement with it you can choose a more aggressive role form him and make the DLP a defend Duty. You should also consider then to properbly change the Fullback to a Suppot Duty. IRL tho most of the Time Goretzka or Martinez was playing besinde thiago in a more defending manner.
FB - In real life on the left wing with Coman and Alaba bayern trys to create overloads as both are very attacking. Alaba is always looking for overlaps and even sometimes underlapping to join the box or at least bring in a cross from byline. So he will be a FB on Attack. Kimmich on the other hand will take place into gnabrys position as he cuts inside to join the box.
CB - Hummels is more like a play opening defender so he will be a BPD and Sule is just a norma CD who will run down attackers :-)
GK - Neuer will be a Sweeper Keeper as he has to cover the space the defensive line will leave behind. He will also be an important part of the build up play.
Ok after we got the Roles & Duties covered lets get to the Team Instructions.
Mentality: As Bayern usually is the stronger team we can afford to player on a more progressive mentality and take more risks to score goals. So we go with Positive.
In Possession: As we want to attack through the Wider areas of the Pitch we choose "Wide" attacking Width. "Play out of defense" and "Work ball into Box" will help us to create a more patient approach in terms of Build up and in craeting goal scoring opportunities. As we have pretty good decision making we can play on a "higher tempo" to leave less time to ur opponent to set up against us. "Standard" passing to be mentioned as we want to keep up oportunities to also play a more direct ball from time to time.
In Transition: When loosing the ball there usually is a short period of time where bayern trys to win back the ball before setteling into defensive positions. So choose "Counterpress". As Neuer is know for his ability to initiate counter attacks with his long throws into wider areas we choose "Distribute Quickly", "Distribute to Fullbacks" and "Throw it long". Also we are perfectly set up for this as "Play out of Defense" will make our fullbacks positiooning higher up the pitch initially because both central defenders will split into wider areas.
Out of Possession: To make our team actually "Counterpress" high up the Pitch (where we usually loose the ball) we need to set up a Higher line of engagement. To not stretch our Team vertically too much we also Higher our Defensive line, covered by an offside trap. As said earlier we want to settle in our defensive shape after a short period of press. So we will keep the overall pressing intesity at a normal level.
I hope i could help you out. By the way this tactic was invented over the course of season and did work very well for me.
