Barca are willing to do business and are already identifying potential replacements.
High on the agenda is VfL Wolfsburg's Belgian keeper Koen Casteels. The 25 year-old is yet to be capped, but has established himself as Wolves' outright No1. Casteels' ground game is particularly attractive to Barca's football staff.
Tim Horn (FC Köln), Tim Krul (Brighton & Hove Albion), Rui Patricio (Sporting Portugal) and Jiri Pavlenka (Werder Bremen) are also being considered. However, it's understood Casteels is the priority for now.
