The father of Shkodran Mustafi says Arsenal need to get serious about their valuation.

Tuttosport says Arsenal have been told to lower their £25m asking price for Mustafi by the defender's father and agent.

“It's best for both sides to work on a transfer but for that it also needs market-driven transfer fees," Kujtim Mustafi said.

Mustafi has been told to find a new club by manager Unai Emery.

Roma and AS Monaco are currently in contact.
