Oleksandr Zinchenko (28, LB, Arsenal)
Zinchenko does not have as many opportunities as he used to have at Arsenal, which is staked at the position with names like Timber, Tomiyasu, and Calafiori available in the left-back position. He would be an intriguing piece in this Dortmund system, especially as an inverted fullback role.
Despite all that, his transfer seems unlikely at the moment. While BVB prefers a loan, sources say that Arsenal insists on a loan with an obligation to buy for 20 million euros. With those terms, Dortmund will probably not tie its future to a 28-year-old left-back option.
