Stated plan

Win the loose c4 pawn with the knight, since it's only defended once and any White recapture leaves Black at least a pawn ahead.

Reasoning

Black's knight on e5 attacks the c4 pawn, which is only defended by the White knight on e3. Capturing wins a clean pawn: if White recaptures with Ne3xc4, Black simply trades knights and is up material; if White instead grabs the f2 rook with Re2xf2, Black recaptures Qxf2 (an even rook trade) while keeping the extra pawn on c4 uncontested. Meanwhile the tension between Rf2 (defended by Qh4 via the h4-g3-f2 diagonal) and Re2 (defended by Qd2) remains balanced regardless, so there's no immediate tactic there for White to exploit. This makes Nxc4 a safe, concrete way to gain material.
