Mainz coach Martin Schmidt admits he's still to find the best position for Bojan Krkic.
Schmidt is battling to find the right role for the on-loan Stoke City striker.
"I think I am satisfied with him. His run was good. But you have to remember that he has not played four months," he said.
"And in Barcelona he has certainly learned a lot - but not how to play for Mainz.
"We've showed him videos of our playing style. In a few situations, he has seen that he can kick it long."
