He played very solid in this half-season. Ok, he still isn't rock in defence, but I think that he will become that in the next season. He was pretty good in defence, but he's poor in attack IMO. Scored one goal, but anyway... Also, this set is mostly with old standards.
Here are my suggestions:
- Spoiler: show
- Attack: 52
Savic is on 53.
Defence: 76
He's solid in dispossesing oponents, but he still has much to improve. He's good with 76, too, so I think that everything higher than this would be too much for now... I don't want to make mistake as I did with Krneta few months ago...
Balance: 83
I rate Jovanovic on 84 and he's stronger a bit than Ostojic.
Stamina: 77
Standarizing. He doesn't move during the match so much.
Response: 77 or 76
He doesn't go out so often to cut passes and something like that, he stays in penalty area very often and I don't know... You decide, Coolactive. 
Agility: 72
Standarizing.
Dribble Accuracy: 69
He doesn't go in dribblings very often and he hasn't such a goodclose control, so this is good for now. Btw, he can succesfully dribble sometimes with this.
I saw him as technical player, but I was clearly wrong.
Dribble Speed: 66
Due his bad close control, he doesn't put much speed on dribblings.
Short Pass Accuracy: 68
He doesn't try such an adventurous passes. He decidedes for a safe choise - Ivanov or goalkeeper.
Long Pass Accuracy/Long Pass Speed: 68/71
His long passes aren't so much accurate, so... I rate Mladenovic at 69, and Ostojic is one point under him. 
Curling: 61
His long passes are very straightly. Btw, even with 65 I noticed some little clues of Curling.
Teamwork: 77
He's got good teamwork with Ivanov. They understand each other very well during the match, he's good at offside trapping,...
