Mustafi's representatives in London ahead of Arsenal move
The agent and father of Valencia defender Shkodran Mustafi are both in London to finalise a deal with Arsenal.
The 24-year-old is expected to sign for the Gunners within the next couple of days and will sign for a fee of around £30m.
The deal will be made up of an initial fee of £25m plus add-ons.
Mustafi previously played in England as a youngster with Everton, but left in 2012 after making just one first-team appearance.
The German has been at Valencia since 2014, where he has played 80 times, scoring six goals.
