The b2 pawn is no hiostory after Kg7 Bxf6+ Kxf6 26.Rd2

The question is what black does after that line.

If black goes for the b2 pawn by 26...Rcb8 then after a possible line like
Rxa5 Rxb2 Rxb2 Rxb2 Ra3 Rc2 Rf3+ Kg7 Rf4 I do not see the win for black.

26...Rc5 is a possible alternative but I do not see how black win it after a
move like 27.h4.
