It has been reported that Mainz coach Martin Schmidt insists Yoshinori Muto won’t be leaving this month.
The Japanese striker has been linked with a move to Manchester United in January.
However, despite Yunus Malli missing out on a move to Borussia Dortmund, Schmidt says Muto won’t be sold.
“The lid is now shut,” said the coach.
United were willing to pay €16 million for Muto.
