Arsenal's first deal of the summer transfer window has been confirmed with VfB Stuttgart announcing the permanent signing of defender Konstantinos Mavropanos.
The Greek centre-back joined the German outfit on a season-long loan deal at the start of the campaign, with a view to a long-term switch. An obligation to buy was written into the contract but would only be active should Stuttgart avoid relegation from the Bundesliga.
With the side avoiding dropping into the second-tier courtesy of a dramatic final day victory over FC Koln - Waturo Endo scoring in the 92nd minute - the clause to make Mavropanos' switch to the Mercedes-Benz Arena became active.
