Rating aslo determine player quality.?As 5* player is more effective than 4*

No, *team's league level and players quallity determine rating.
For example, player has quallity 27.
Then his possbile rating is:
6 stars for level 1
5 stars for level 2
4 stars for level 3
3 stars for level 4
2 stars for level 5
1 stars for level 6 and above

* Do not misjudge level of the manager and level of the club. Level of the manager shows highest ranked league he played, while teams level shows on which league level is his club now.

I keep some 4* players which have good form consistency and/or whose quallity is near 5*. Besides that, I don't have habit or will to spend much tokens every season to improve squad a bit, to change many players. Sometimes it also depends of players growth, age, contract lenght and even other players on same position. Usually 4* players are substitutes or reserves in my team. However, it might happen that I keep 4* player in 1st team, like I did last season where my 4* right winger was club's top scorer and 3rd top scorer in league. Players quallity doesn't guarrante his good form.
In my team called Dnipro there is 4* AML-AMC corner specialist who has 164 caps, 66 goals and numerous assists because he has been 1st corner taker from his 1st match in the club. (sadly TE doesn't keep full assist stats like they keep for goals). I think I might spend some greens to improve him back to 5* if his growth is still somewhat good because he has been very important player for seasons in my team.
