The Germany international has been heavily linked with the Gunners of late, with suggestions that a deal could be done by the end of the week doing the rounds.
Although Valencia are somewhat digging their heels in to keep hold of the Germany international, reports claim that they are seemingly aware that retaining the 24-year-old may prove too big of a task, and Mbemba is an option to come in.
The DR Congo ace was one of few players to emerge from Newcastle’s relegation last season with his reputation intact following his summer 2015 move to the club from Anderlecht.
The 22-year-old is valued at around £7m.
Mbemba started the Magpies’ shock weekend loss at home to Huddersfield after missing their opening defeat at Fulham.
