Multiple reliable news outlets have reported that the race to sign Antonio Rudiger is heating up, as reports indicate that Galatasaray have now officially submitted a bid for the player as they look to strengthen their squad ahead of the run-in. Talks are expected to continue over the coming days - with Real Madrid said to be reluctant to let him go for a penny less than their valuation. AL Nassr, Paris SG and Chelsea are reportedly waiting in the wings. Finalising a fee and payment terms remains central to closing the transfer. Galatasaray's back line has been a real strength this season, conceding just 0.71 goals per game (12 in 17). Antonio Rudiger would be expected to slot into that unit and hold his own in an already solid setup. Real Madrid have also been linked with Marcos Senesi, Nico Schlotterbeck and Kees Smit while Galatasaray are reportedly monitoring Davide Frattesi and Manuel Ugarte.
