How to turn off opponent mic in ps4?

Hi every one yesterday I was playing fifa 15 and some one cussed so much because I was beating him and other was complaining about my tactics so I had to mute the tv to be able to focus in the match but I also would love to wear the match commentary and fans crowd while I am playing, so can any one please tell me how can I mute the opponent mic because seriously its was pretty annoying and made me nervous until I lost a match from other opponent who was pretty quite in that match.

Thanks every one and sorry for my long topic I just wanted to share with u guys.
