The Argentina striker had scored just once in his previous nine appearances, but found the net along with Cristiano Ronaldo, Luka Modric and substitute Karim Benzema as Real rattled in three goals in five second-half minutes.
Modric lashed in a superb right-root shot to put Real ahead -- another vital goal after his superb effort against Manchester United in the Champions League which helped earn Madrid a quarterfinal clash with Turkey's Galatasaray.
