Waldemar Anton has reportedly emerged as a transfer target for Atletico, with the LaLiga side said to be eyeing a move for the Dortmund defender. Speculation is gathering pace as the club looks to bolster its squad ahead of a crucial second half of the season. While Atletico and Dortmund continue talks, no breakthrough has been reported. Man Utd, West Ham and Aston Villa reportedly may still have an interest, but currently the focus is on getting this deal across the line. Atletico's back line has been a real strength this season, conceding just 0.97 goals per game (28 in 29). Waldemar Anton would be expected to slot into that unit and hold his own in an already solid setup. Dortmund have also been linked with Archie Gray and Jadon Sancho while Atletico are reportedly monitoring Aleix Garcia, Gabriel Martinelli and Gabriel Jesus.
