SC Freiburg chief Klemens Hartenbach is aware of rumours linking Arsenal with Caglar Soyuncu.

However, Hartenbach insists there's been no formal contact from the Gunners for the defender.

"We received no request from Arsenal," he told Badische Zeitung, having also insisted talk of a £30m valuation was too cheap.

"You'd have to put a bit more on that."

Hartenbach added: "We agree that Caglar should play for us in the upcoming season."
