That´s the right way, which costs some money. But you better buy playerswhich earn only 1100...
other way is just playing 5 players in srimmage, on the other hand, if one on a trainings position will get hurt or fouled out, you´ll train the lucky fan ;-)
Salary doesn't matter for that purpose because I'll fire him after the match...
Playing only 5 players doesn't help me if my players already have 40-50 minutes for that week and I need them to play nother 10 or 20...
We have both said a lot of things that you are going to regret.
