6) Ilkay Gundogan
Still only 24, this Dortmund playmaker could be a massive coup for any number of sides. The German international has proved himself to be an exquisite technical player with a wonderful passing game, meaning that he could fill a gap for several Premier League sides come the summer.
5) Ciro Immobile
The Italian international only joined the club in the summer. He was meant as a replacement for Robert Lewandowski but as struggled to adapt to life in Germany, scoring just three league goals in 17 appearances. He has managed seven more in cup competitions but should still go.
