My favorite players who have doubled as the best in my squad for several seasons now, both of whom were signed a 18yo —one, an MC and the other an AML [now best ever goalscorer with 118 goals, and 2 assists away from being best all time assister] — are 24yo this season.
They're beginning to decline in stats even though they still have very high skills. Makes me wonder if that's the end and this is what happens to players bought at 18. If there's a max number of seasons (5-6) for which players can be brilliant.
Context: Currently have a 27yo signed at 25yo who remains as good as when he first arrived. Signed an AML at 22yo once who went on to be brilliant until 26yo.
