Werder Bremen chief Clemens Fritz admits they've been impressed by trialist Kallum Cesay.
The defender is off contract from Tottenham and has spent the week with Werder.
Fritz told BILD: "He did well both athletically and personally. It's not easy to get into a solid team as a young player. He also knew that he was being watched closely. He made an open impression.
We will talk to his agent.
"But for now, no final decision has been made about him."
