Multiple reliable new sources are reporting that Paris SG have submitted a concrete bid for William Saliba. The defender remains under contract at Arsenal, but the opening offer has opened the door for discussions between the two clubs - though it is unclear at this stage whether the current bid will be enough to tempt them to part with a prized asset. Real Madrid may look to intervene if talks continue without resolution. Paris SG's back line has been a real strength this season, conceding just 0.86 goals per game (25 in 29). William Saliba would be expected to slot into that unit and hold his own in an already solid setup. Arsenal have also been linked with Endrick Felipe Moreira de Sousa, Joaquin Seys and Ibrahim Maza while Paris SG are reportedly monitoring Mateus Fernandes, Gabriel Martinelli and Lewis Miley.
