[I need help with choosing what players to sell/keep [Long post]]

I would agree with everything above. Hey to get rid of Youssouf as he is overpaid ans injury prone. I would suggest trying to offload who you can and finding better players for less money. 

As it stands right now I can see a Bad financial Situation coming up. You are 70 million in debt and need to cut costs.

Ok got it. But I have a few questions?

Which league? Which Team? Board expectations?

Facility Level? Financial Situation? 

Are any of them not constant or afraid of big games?

Do they under-or overperform?

What is your long term Plan?  

Do you play with or against the ball?

How does your team compare to the league?

Are there any youngsters coming up?

Right now I would suggest trying to sell Verbrugghe.

I find it funny how I can't believe those numbers. I am paying my squad (AEK) in a month what Vorm gets per week.

Ohh ok thanks for the info.

Then you should be able to get them into the 3rd tier

In Real Life a 2. Team can't get higher than 4th Tier, which is not a proffesional league. As I have never seen one in FM I believe it is the same. 

But you could loan out your players to third-tier clubs, which always need loans as their budgets are strict.
