Chelsea are believed to be interested in bringing Barcelona youngster Sergi Roberto to Stamford Bridge.
The 19-year-old midfielder is thought to be available for £5m with a buy-back clause if the former Premier League champions decide to sell on the teenager, according to talkSPORT.
Roberto signed for the Champions League winners when he was fourteen and has made one appearance for Pep Guardiola's first team.
The playmaker also has one cap for Spain's Under-21 squad.
