According to the same story, Martinez has put pen to paper on a four-year deal with Aston Villa ahead of completing his move to the Birmingham side to end his long association with Arsenal.
Earlier this summer, Aubameyang was holding out for offers from other clubs including Barcelona.
However, with Matt Macey also being linked with a move away from the Emirates, there is a chance Arsenal are bringing in Runarsson as a third-choice goalkeeper and are still on the hunt for a Martinez replacement.
Aubameyang tweeted an egg timer to tease supporters that official confirmation on his new deal is expected shortly.
Arsenal are interested in making a move for Icelandic worldwide goalkeeper Runar Alex Runarsson, according to reports.
Chelsea were monitoring Aubameyang's situation in January and were preparing a shock move for the Gabon worldwide.

Arteta's men are next in Premier League action in Saturday's late game against West Ham.
