Mainz manager Christian Heidel has played down suggestions that Adam Szalai could soon be on his way to Arsenal.
The 25-year old Hungarian striker has emerged as a target for the Gunners but Heidel says there has been no official interest lodged.
"Arsenal haven't contacted us," said Heidel.
"We don't want to let our striker go in the winter transfer window. But that's another situation if someone willing to pay 20 million Euros for him."
