Valencia owner Peter Lim has flown into London.
Plaza Deportiva says Lim is travelling from Barcelona, where he is on other business, to finalise Shkodran Mustafi's transfer to Arsenal.
Following his arrival in England by private jet, It's suggested Lim will hold a meeting with Arsene Wenger to thrash out the deal.
Mustafi has reportedly agreed a five-year deal worth £75,000-a-week with Arsenal.
The 24-year-old has a £42m release clause in his contract but the La Liga outfit are willing to accept £30m, says the Daily Star.
