Sometimes, 1 step back to take 2 steps forward is the only way to go! Example:
Im in a save with Wolfsburg at the moment, and I have built my team around Diego, as he is a quality player. Problem is, he is on £100,000 a week, when my entire spend on wages is £700,000 per week!! Next highest earner is on £55,000, which is all I really want to pay. Even though he is a great player, Im going to have to let him go at the end of the contract as could use that £100k much better for the overall squad.
