Chelsea boss Andre Villas-Boas has assured fans Barcelona cannot take Oriol Romeu back to the Nou Camp in June.
The clause in Romeu's deal simply entitles Barca to 'first refusal' should Chelsea decide to sell.
"The buy-back option states that Barcelona can only buy back if Chelsea are willing to sell," clarified Villas-Boas, who also discussed Romeu's quick acclimatisation to England.
"There is always time needed for you to adapt into the Premier League but with Oriol Romeu and Juan Mata, and Raul Meireles last year at Liverpool, these players have adapted pretty well to Premier League standard. They have all set standards of quick adaptation to this level."
