Hi everybody! Is the sentence above an idiom? What does it mean? Here is a little bit of context. Tony has just realized he is in love with a woman. The sentence is: "His father coming by today had just been the brick to the side of the head he needed to knock some sense into him. My attempt: La visita di suo padre di oggi era stata il colpo che gli ci voleva (???) per inculcargli (o fargli venire) un po' di buon senso. Is it correct? Thanks in advance.
