LB: Alex Telles (Porto)
Telles is regarded as one of the most talented left-backs in Europe and has plenty of pace and skill. The 25-year-old Brazilian may have scored just four goals, but has managed a staggering 19 assists, five more than the Championship assist king Barry Douglas.
High on Wolves' wishlist, he has previously been a target for both Chelsea and Liverpool. A transfer looks highly likely and Santo is a keen admirer and could swoop for his signature.
Alternative option: Barry Douglas (Wolves) - a consistent performer, is expected continue at full-back in the Premier League, but could be seen as a backup should Wolves sign Telles. He could also challenge Andrew Robertson and Kieran Tierney for Scotland's left-back role.
