Is there something like good performer in TOP ELEVEN

[RaiKo]

No. The players have internal skills. When you buy a player, the engine calibrates your team so you cant buy 11 players that scored 40 goals each one last season and expect the same.
The engine will assign internal contributive roles, as key player, assister, a FK man role that will stay attached to aplayer few weeks, another for corners, animations/actions assigned to players...

This info was a real game changer for me. I didn't know it was like this. Does it mean there are not pre-programmed players in the game ? As much as i understand, every time players are
initially re-programmed according to their new signed teams situations(good performer cap). May be set based on low or high performance, the chance depends on how many good players you have before new signing.

If i transfer my opponent legend player, he might be underperforming in my team or Player stats are not important when you decide to buy a player. Can you explain more please ?
