Nelson Weiper

In January 2026, reports concerning Werder Bremen's interest referenced a valuation of approximately €14 million set by Mainz in the summer of 2025. During August 2025, a potential fee of €14 million plus bonuses was mentioned, while Eintracht Frankfurt reportedly planned to bid about €10 million. In July and June 2025, Mainz's asking price was consistently reported as €14 million (or the equivalent £12 million) amid interest from several Premier League clubs and Como.

Our valuation for Nelson Weiper is primarily shaped by the consistent reports from summer 2025 stating Mainz 05's asking price was €14 million, contrasted with a planned bid from Eintracht Frankfurt for around €10 million. His subsequent contract extension to 2029 significantly strengthens Mainz's negotiating position, supporting an estimate towards the higher end of this range.
