Mustafi has a release clause of £42.1m but Sky Germany understand that Arsenal may be able to sign the German for £25.3m plus a further £8.4m in add-ons.

Mustafi trained with his Valencia team-mates for the first time on Thursday following his post-Euro 2016 break and his agent is expected to fly to Spain to discuss the transfer fee with Valencia.

Arsenal manager Arsene Wenger admitted last week that he needed to sign another centre-back, despite bringing in Rob Holding from Bolton, due to a long-term injury to Per Mertersacker.

Former Everton defender Mustafi has been with Valencia since 2014 when he transferred from Sampdoria and has made over 60 La Liga appearances.

He also has 12 caps for Germany since his debut in 2014, and impressed at centre-half during Euro 2016 in France.

Mustafi previously was an Everton academy graduate but failed to make a first-team appearance before leaving in 2012.
