Transfer talk surrounding Nathan Ake is intensifying, with reports suggesting Barcelona are monitoring the Manchester City defender closely. The player has caught the attention of several scouts as other clubs prepare for a potentially active transfer window. Bournemouth, Crystal Palace and Tottenham may look to intervene if talks continue without resolution. Barcelona's back line has been a real strength this season, conceding just 1.11 goals per game (20 in 18). Nathan Ake would be expected to slot into that unit and hold his own in an already solid setup. Manchester City continue to be linked with Harry Gray, Daniel Munoz and Pedro Porro while Barcelona are also rumoured to be tracking Marcos Senesi, Josko Gvardiol and Pau Torres.
