According to multiple sources, negotiations are underway regarding Alex Grimaldo, with Atletico keen to finalise a deal with Leverkusen as they look to strengthen their squad for the run-in. The defender has emerged as a top transfer target in recent weeks, and the player's representatives are also believed to be involved in early discussions on personal terms. Whether a deal can be struck remains to be seen, but there is increasing optimism that the transfer could go through in the coming days. Chelsea, Besiktas and Barcelona are reportedly waiting in the wings. Finalising a fee and payment terms remains central to closing the transfer. Atletico's back line has been a real strength this season, conceding just 0.88 goals per game (23 in 26). Alex Grimaldo would be expected to slot into that unit and hold his own in an already solid setup. Alongside this, Leverkusen are said to be exploring Afonso Bastardo Moreira with Atletico likewise connected to Tijani Reijnders, William Gomes Carvalho Santos and Nicolo Tresoldi.
