Sunderland have made a return offer for Dynamo Kiev forward Jeremain Lens.

The Black Cats had an initial bid of £8million turned down by the Ukrainian side but according to the Daily Mail, will offer £9m as they look to land the Dutchman.

Dick Advocaat worked with Lens at PSV Eindhoven and has identified the 27-year old as one of his key summer targets.

Lens, who is contracted with Kiev until the summer of 2017, scored 27 goals in 61 appearances under Advocaat during their time together at the Philips Stadion.
