William Saliba has reportedly emerged as a transfer target for Barcelona, with the LaLiga side said to be eyeing a move for the Arsenal defender. Speculation is gathering pace as the club looks to bolster its squad ahead of a crucial second half of the season. While Barcelona and Arsenal continue talks, no breakthrough has been reported. PSG and Real Madrid reportedly may still have an interest, but currently the focus is on getting this deal across the line. Barcelona's back line has been a real strength this season, conceding just 1.0 goals per game (26 in 26). 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 Aaron Wan-Bissaka, Crysencio Summerville and Jules Kounde while Barcelona are reportedly monitoring Ayyoub Bouaddi, Bradley Barcola and Alexander Isak.
