nike tennis apparel Michael Stich collection

Hello there, I'm a collector of the vintage sports apparel. I'm particularly interested in Nike collection from 1997 worn by german tennis star Michael Stich. The collection is in red and blue colour. Could someone please provide any information where could it be found or if you know someone who perhaps has it. I can offer a great price, since I've been looking for for years. please refer to the photo in the attachment.

With respect
