The 10 best players Chelsea could still have at the club, with Sturridge & Courtois

6) Marko Marin – Sevilla (On loan) 

The German flyer is fit again, and back in the Sevilla side. He was never given a chance at Chelsea, despite showing excellent potential and talent in the Bundesliga with Werder Bremen. He won caps for the excellent German national side when he was only 19-years-old, showing he has the potential to develop into an excellent player under the right guidance.
