Apologies if this is a topic which has previously been brought up on here. Am I correct in understanding that when players retire, you will need to replace them with players purchased from the auction house?
The retired player will automatically get replaced by a substitute player post by post. In the case you've only 15players in your team, the retired player will get replaced by a 6 stars new player. Then you'll need to purchase a new one.
If you have only got 15 players before retirement then you have got a problem given the impact of substitutions in the game. In the past it did occasionally generate younger 6* by continually dismissing the replacements but it was not very often. Not tried it in a long time so not sure if still the case.
Does this in essence result in crazy bidding wars for younger talent higher up the leagues? With the few generated youngsters going for silly prices for to desperate teams
