Sunderland boss Dick Advocaat has also been adding to his squad. The Black Cats have signed Netherlands midfielder Jeremain Lens from Dynamo Kiev for £8m. The 27-year-old, who has joined on a four-year contract, worked with Advocaat at AZ Alkmaar and PSV Eindhoven. If you want to know what sort of player he is, he’s quite happy to tell you. “My qualities are that I’m fast, I can score goals and I can create chances,” said Lens. Lens is Sunderland’s third signing of the summer after the arrivals of defenders Adam Matthews and Sebastian Coates from Celtic and Liverpool respectively.
