Stated plan

Capture the undefended d5 pawn with the king, since f8 is already blocked against promotion.

Reasoning

The f7 pawn cannot actually promote since Black's rook already occupies f8, blocking it. Meanwhile White's d5 pawn is undefended (the e3 rook doesn't guard it), so Black can safely grab it, centralizing the king and eliminating White's passed pawn.
