The Welsh star is back on the treatment table following last season's injury-hit campaign and according to a report in El Confidencial, the Spanish champions are losing patience in him.
While the 28-year-old has consistently stated that he is happy to remain at the club, the report suggests that Jose Mourinho is keen to snap him up at Manchester United and Madrid would be willing to sell him, should they recoup the £85million they shelled out for him.
