We've got a new, brilliant left-back in Alba, and Montoya is his perfect counterpart. They're like Alves and Abidal reversed. It's time to let go of the Alves+Abidal idea and use the squad in the best way possible. We can still get decent money for Alves, and I believe many clubs would be interested in him, so we should take the opportunity. If Alves leaves (and Adriano stays), we'll have Alba, Montoya and Adriano for fullback spots, which means we could get away with either buying a cheap right-back (a RB/CB type of player would be perfect) or, the more risky option, sticking with just Adriano as the backup for this season.
