The Blues are hopeful that Slobodan Rajkovic will finally get his work permit after four years of being a Chelsea player.
The Serbian moved to England from his hometown club OFK Belgrade in 2007, but has yet to be allowed to play in England.
He has spent the last three years on loan with PSV, Twente and then Vitesse last season and has played for the national team six times. During the 2010-11 season, he made 24 appearances in the Dutch league.
Having seen Raijkovic impress during the pre-season tour in Asia, Andre Villas-Boas is very keen to be able to include the player in his squad for the upcoming season.
