Chelsea are set to seal the signing of Barcelona youngster Oriol Romeu.
The 20-year-old is set to finalise a move to Stamford Bridge with Chelsea offering €5million.
Barca sources have confirmed to skysports.com that talks are on-going but a deal is imminent.
Spanish sources also claim that Barca will have a clause in the deal inserted which will allow them to buy highly-rated Romeu back in the summer of 2013.
Romeu is believed to be a long-term target of Chelsea boss Andre Villas-Boas and the Portuguese coach was trying to sign him for Porto before he moved to West London.
Romeu, who was also believed to be a target for Arsenal, is now set to fly to England in the coming days to finalise the move.
The 20-year-old, a Spanish youth international, made his senior debut for Barcelona in La Liga at the end of last season.
