Chelsea are interested in signing Sunderland midfielder Granit Xhaka in a surprise move that would reunite him with manager Xabi Alonso, the Press Association understands.

The Switzerland international, who is currently with his country at the World Cup in North America, was the outstanding player last season for the Black Cats as they made a stunning return to the Premier League, finishing seventh to qualify for the Europa League.
