Jose Mourinho expects Chelsea to sign a left-back before the end of the transfer window.

The Premier League champions, who sold Filipe Luis back to Atletico Madrid this summer, look set to agree a move for Augsburg full-back Baba Rahman and Mourinho confirmed that he is keen to bolster his defence before the window closes.

"We need a left-back, the board knows that and my feeling is that we are going to have one,” he said.
