Sunderland have secured the capture of Dynamo Kiev forward Jeremain Lens on a four-year deal.
The fee for the 27-year-old Netherlands international was not disclosed.
Lens has previously worked with Sunderland boss Dick Advocaat at PSV and AZ.
“We have signed an international player and I am delighted to welcome him to Sunderland,” Advocaat told his club’s official website.
“He is a very well-known player in Europe and has played 30 games for the Dutch national side, which shows his calibre.
“I have worked with him twice already, at PSV and AZ, so I know him well; he is fast and he has scored goals everywhere he has played so that will help the team.”
Lens has eight international goals to his name and was part of the Netherlands squad that reached the semi-finals of the 2014 FIFA World Cup, having scored five times during qualification.
He is the third close-season arrival at the Stadium of Light, following the signings of defenders Adam Matthews from Celtic and Sebastian Coates from Liverpool.
