Arsenal are stepping up their summer business, with the Guardian reporting that the Gunners have agreed a deal worth up to £34m (€40m) for Christos Tzolis, according to EPL Index.
The move comes amid growing fitness concerns over William Saliba, which are reportedly shaping Mikel Arteta's transfer strategy this window. With question marks over the Frenchman's reliability at the back, Arsenal are said to be looking closely at bolstering their defensive options from within the Premier League itself.
While the Tzolis agreement appears to be progressing, the report also links Arsenal with interest in a Premier League defender, though specifics on the player's identity and the size of any potential deal remain unclear at this stage. As it stands, this remains firmly in speculation territory rather than a confirmed pursuit.
Arsenal's recruitment plans this summer look set to be defined by squad depth and dealing with Saliba's fitness situation, with further defensive reinforcements not ruled out should the right opportunity present itself.
