Nelson Weiper

Most recently, in July 2026, reports cited an estimated market value of €7 million. In January 2026, rumours referenced a valuation of approximately €14 million set by Mainz during the summer of 2025. During that period, in August 2025, a potential fee of €14 million plus bonuses was mentioned, while Eintracht Frankfurt reportedly planned a bid of about €10 million, and another report suggested a 'high single-digit million' fee. In June and July 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 shaped by conflicting data points. A year ago, amid strong Premier League interest, Mainz 05's asking price was consistently reported at €14 million. However, more recent reports from July 2026 cite a market value of just €7 million following a 'dissatisfying season', with interest now coming from the Austrian Bundesliga. While his long-term contract until 2029 provides Mainz with leverage, the player's desire for a move and cooled interest suggest a fee closer to the lower end of the historical range.
