According to various outlets, Sunderland are seriously considering a move for Dortmund defender, Julian Ryerson. While nothing concrete has emerged yet, the player's name has reportedly featured in internal discussions about possible reinforcements ahead of the run-in. While Wolves have shown interest, Sunderland currently lead the race - though the situation could evolve if a deal drags on. Sunderland's back line has been a real strength this season, conceding just 0.86 goals per game (6 in 7). Julian Ryerson would be expected to slot into that unit and hold his own in an already solid setup. Alongside this, Dortmund are said to be exploring Leandro Trossard, Juan Gimenez and Idrissa Gueye with Sunderland likewise connected to Baris Alper Yilmaz. Want to see how the story develops?
