Mainz chief Christian Heidel insists they're under no pressure to sell Jean-Philippe Mateta this month.
The striker is being linked with Leeds United as they seek cover for Patrick Bamford.
Speaking to Kicker, Heidel laid down his understanding of the situation surrounding the 23-year-old's future.
"As of today, there won't be any change," he insisted.
Along with Leeds, Southampton and Tottenham made enquiries after Mateta over the summer.
