Sunderland are having to deal with a lot of defensive changes already this summer.

Sunderland defender Younes Kaboul's unexpected eagerness to return to London for family reasons, leading to the Frenchman departing the Stadium of Light to return south in what is expected to be a £3.5 million move to Watford (Sunderland Echo), hasn't just caused a headache on Wearside, it has also made Everton's pursuit of Lamina Kone that much harder.
With the Toffees selling John Stones last week it looked as if they were to quickly bring in both Ashley Williams and Kone to make up for the England international's departure.
But though the Swansea captain swiftly sealed his move, Kone's possible transfer became something of a mess.

The former Lorient man seemed eager to move, pointing to Sunderland's failure to offer an improved contract as reason to push for a leave (Sky Sports), while the Black Cats looked to be convinced into selling the player.
But the prospect of Sunderland selling both of their first-choice central defenders is slim to say the least, and David Moyes may find himself having to build bridges come the end of the transfer window unless Ronald Koeman returns with an offer the Black Cats cannot refuse.

Everton have in truth already been linked with other central defenders since the early stories broke regarding the expected transfer of Kone to Goodison Park, hinting that they are already looking elsewhere given the difficulties in doing a deal.
The Ivory Coast defender does not seem to be as quick to move on though, and Moyes confirmed on Friday (Sky Sports) that Kone has refused a contract offer this week.
Who knows what will happen come the end of the transfer window, but as of now, things are looking far from simple.
