Their relative qualities will decline gradually.
I can give you a rough idea through an illustration.
Every uninjured player can gain 40% condition daily. Assuming high intensity practice match consume 15% condition. If you have a fast trainer who can gain 100 training progress (i.e. 1sp) through high intensity training. The sp he obtain daily = 40/15 = 2.67
To gain one star, 75sp is required. So the no. of days to increase 1 star = 75/2.67 = 28 days = 1 season.
Certainly, training progress gained through real matches may not be the same as training. Many other factors affect this estimation like extra green packs used, time lost on injuries, etc.
You should also understand training progress slows down after gaining a star, and increases after losing a star due to promotion to higher level in new season even if players are one year older. If a player is 6 star or above for prolonged period in a season, his training progress gained in the season will be less.
In my opinion, keeping some young players to play for a few seasons is good. With very difficult auction markets, 35T managers are hard to rebuild large part of a team every season.
