Jose Mourinho delighted with Baba Rahman capture

Chelsea manager Jose Mourinho has welcomed the arrival of defender Baba Rahman and has admitted that he has high hopes for the young left-back.

The 21-year-old's move to Stamford Bridge for an undisclosed fee was announced less than an hour after the Premier League champions lost 3-0 at Manchester City today.

With Filipe Luis returning to Atletico Madrid earlier this summer, Mourinho hopes that Rahman can be the man to challenge regular left-back Cesar Azpilicueta this term.

"It's important because he is a left-back and he can compete with Azpilicueta," the Portuguese told reporters.

"At the same time, by being a left-back, Azpilicueta can compete with [Branislav] Ivanovic for the right-back position.

"This player replaces Filipe Luis in the balance of the squad. He is a player that we need for that balance."

Rahman, who left Augsburg in Germany to join the Blues, is also a Ghana international.
