Advice on team

I apologize if this is annoying but can you please recommend improvements to my team?
I seem set to me for the rest of the season, but would like to fine tune my team.
Any suggestions?

It depends on how strong your opponents are.

I mean, I've seen leagues where all managers have very average teams all below yours, while in other leagues most managers have teams as good or better than yours.

I would buy one more ST -not for much money, just a 5* veteran for back up. 3 GK are too many. I 'm using only one good for every game and have another 3* just for sub emergency.
There are some games that you must use 2-3 ST. 4-5-1V is good but try to find also other formations.
