The Spanish giants are determined to get Bellerin back to the Nou Camp but know he will not force his way out of the Emirates.
The full-back, 22, still has six years left on the £100,000-a-week contract he signed in November and does not want to rock the boat, despite losing his place in the team.
Rafinha, 24, is looking to leave Barcelona for regular first-team football, although he has been out since an April knee operation and could miss the start of the new season.
