Notice how unbelievably meagre young players' stamina stats are in FM ? How are they supposed to last past half time ? 
 
This is also true of players of any age in FM as well. IMO, this is a weak spot in SI's game model & always has been. The amount of times the opposition I've been playing has made at least 2 subs at half time is unreal ( not for any tactical or injury reason, you understand, but because they're too shagged out to continue ! ).
 
The stamina stat is the only stat that I have no concerns about editing to give a more realistic number to ( so that, abw, a player will last upto the 65 min mark at least ! ).
