Augsburg manager Stefan Reuter confirmed Saturday that Ghana's Abdul Rahman Baba is poised to join English champions Chelsea with the deal set to net the Germans up to 30 million euros ($33m).

"All that is missing is the signature," said Reuter after Augsburg's 1-0 defeat to Hertha Berlin on the opening weekend of the season.

The left-back was missing from Augsburg's matchday squad against Hertha having undergone a medical check for the Blues in Paris while a British work visa is arranged.

The Blues have targeted the Augsburg defender following the departure of Brazil defender Filipe Luis to Atletico Madrid after just one season at Stamford Bridge.

The 21-year-old Ghana international cost Augsburg just 2.5 million euros ($2.7m) when he joined from Greuther Fuerth in 2014 after signing a five-year contract.

The transfer fee is set to be £14 million (19.8 million euros, $21.9m), with further bonuses of up to ten million euros built into the contract, depending on Rahman's number of appearances for Chelsea and the London club's future success.

Rahman has made 13 appearances for the Black Stars and played in the African Cup of Nations defeat to the Ivory Coast on penalties in the final in January.
