Chelsea have agreed a deal for the Augsburg left-back Baba Rahman.

The German club’s general manager, Stefan Reuter, said: “Baba Rahman has developed tremendously in his year with us and made a great leap. It’s not just reward for his achievements but also for our work, if international giants like Chelsea are interested in signing him.”

Rahman played 31 games for Augsburg last season after joining from the German second division side Greuther Furth.
