Shkodran Mustafi is reportedly set to leave Arsenal this summer if an interested club meets his £22.3m valuation.
The German centre-back joined Arsenal from Valencia for over £35m in 2016 but has failed to nail down a starting spot at the North London side.
Galatasaray and Juventus have been linked with the 26-year-old, but The Mirror reports that Arsenal will only sell on a permanent basis.
The arrival of Sokratis Papastathopoulos has added competition for Mustafi under new manager Unai Emery, and the defender may look for more playing time elsewhere.
Mustafi, who won the World Cup with Germany in 2014, has netted five times in his two seasons with the Gunners.
