Arsenal defender Konstantinos Mavropanos is set to sign for Stuttgart.
The centre-half has been on loan with the German club this season.
According to Fabrizio Romano, the club are eager to activate a buy option within the loan agreement.
The two clubs will now hold talks, while Mavropanos will discuss a contract with Stuttgart as well.
If everything goes according to plan, the deal could be concluded for roughly £2.7 million.
The deal can now be ratified as Stuttgart have assured their status in the Bundesliga for another season.
