Aberdeen have confirmed that Maceo Rigters is training with the club. Celtic tried to sign Rigters in 2007 after the striker starred in Holland's successful European Under-21 Championship campaign, but Blackburn beat him to his signature.
However, Rigters failed to make an impact at Rovers following his move from NAC Breda, making just eight appearances over the course of his four-year contract.
The 27-year-old spent last term on loan at Willem II in his homeland before his Ewood Park deal expired.
