Man Utd Transfers - 5 Right-Back Alternatives To Bacary Sagna Van Gaal Should Sign

3. Lukasz Piszczek

While Southampton are trying desperately to cling on to their best players, so too are Borussia Dortmund, who are gradually being stripped of some of their best stars. Mario Gotze left to join league rivals Bayern Munich last summer while star striker Robert Lewandowski will do the same thing this summer, and now, ukasz Piszczek is having his head turned with Arsenal reportedly interested. And when it comes to signing a new right-back, United too must surely be interested, with the 28-year-old excelling for his side in recent seasons, helping the Germans reach the Champions League final in 2013. And though the defender struggled with injury for much of last term, there is no questioning his talent. Could he join Shinji Kagawa in swapping the Black and Yellows for the Red Devils? The Pole would fit perfectly into Louis van Gaal's system at Old Trafford, given that the defender plays attacking football having initially started his career on the wing and up front, and currently plays as an attack-minded right-back at Dortmund.
