Abdul Baba Rahman has signed a one-year extension to his Chelsea contract ahead of leaving on loan for Real Mallorca.
Left-back Baba, who joined Chelsea from German side Augsburg in the summer of 2015, divided last season between loans at Schalke in Germany and then Reims in France.
It was while with Schalke in 2016/17 that he suffered a serious knee injury sustained playing for Ghana at the Africa Cup of Nations, bringing that season to an early conclusion.
When ready to play again, he returned to the Bundesliga club before the January switch to Reims where he played 11 games.
