Maybe his Attack is a bit low... 58-59 can be good for him.
I see OK his Defence, maybe he's the best CB of 2. Bundesliga but Header can be a little higher: 82-83.
Pass skills are OK to me but SA and Place Kicking must be lower. I suggest 60 & 60.
Now I see his Response a bit high. 77 can be interesting for him.
He's a damnit beast so Body Balance can be higher. I suggest 85-86.
I have no problem with low yellows in Stamina: 81-82. Phisically he's a buffalo...
But his Teamwork could be lower 'cause sometimes I see him a little anarchic. Deniz Dogan is better than Bikakcic in this skill. He deserves no more than 70-71.
And Shot Technique 61-62.
The intelligent people are full of doubts while the stupid ones are full of confidence.
