after the game on Saturday we were planning to extend the trial so im guessing the boy thought we should give him a deal now or he was going home.
Mcinnes said "For Berkay and Scott McKenna at the back, there was not a lot for them to do, but I thought what he did do was absolutely fine and he was tidy enough with his work," said McInnes.
"He's done well this week in training and it's no secret we are looking for a centre-back.
"But he is one of a few that we are looking at and we have the luxury of having a look at him by giving him some training facilities this week.
"We'll keep him with us for the next wee while and we'll see where we are."
So I suspect that possibly even though we wanted to continue with a trial over a longer period of time that maybe if he has a deal on offer from a team back in Germany that he has decided that rather stay on for a longer time here and quite probably end up with nothing he will be better to take what's on offer back home so he has some certainty over his future.
