New to FM. Need tactical insight.

Hey guys. I m new to FM and I started in Bundesliga with Leverkusen. Game is really hard by the way 😀 . I tried to make my own tactic and its not really working. We cannot score for our lives. We cant beat the teams that we should beat. Can you take a look at the tactic and tell me whats wrong and why and what should be done. Thank you all !

I'm not familiar with Leverkusen's players but I'll give it a shot. With more info you could get better advice (e.g. are you losing lots of games, or just not able to score and drawing instead? What areas of the pitch are you conceding goals from/goals being assisted from? Are you conceding lots of goals from counter-attacks?) but I can see a couple of areas that could be improved:
 

• Both flanks have the same Roles and Duties (W-At and FB-Su). Maybe one side could be changed to W-Su and FB-At, or even WB-At or WB-Su to provide different attacking patterns.
• You don't have a holding midfielder. BWM-Su is a player role that runs around a lot trying to win the ball back, and with a CM-At alongside him it leaves your own midfield with lots of gaps for the opposition to exploit. Aránguiz could be changed to CM-D to help with this.
• You don't have a playmaker role. This isn't always necessary, but if you're lacking creativity it could be worth trying. Possible options could be Wirtz changed to AP-Su, or Aránguiz to DLP-D, or Vargas to AP-At depending on which players' attributes are best for the role.
• If you're giving away lots of chances to counter-attacks you might want to reduce the mentality to Positive, or drop your line of engagement to make the team more vertically compact, so the midfield and wingers won't be pressing so high up the pitch and leaving large gaps in behind. By default, Attacking mentality will also increase the Tempo of play, so players will try and progress the ball up the pitch and pass quicker - if you're having trouble unlocking a defence, the slightly reduced Tempo of Positive mentality might help.
• The Pass Into Space instruction: If you're pressing high up the pitch with the higher defensive line and line of engagement as well as Attacking mentality, you're restricting the space in which the opposition will be in, and if the opponent is a team sitting deep, waiting for your players to make a mistake and then hitting you on the counter-attack, then you won't have much space to pass the ball into. Try seeing how your team plays if you remove that instruction.
