Georges St Pierre has told Matt Serra to take a good hard look at Matt Hughes before he heads to Montreal to defend his Welterweight title at UFC 83 on April 19.

St Pierre is adamant he will never lose to the same opponent twice in his UFC career, and it is hard to argue with him when you look back at how he responded to his only other defeat, against Matt Hughes.

The Canadian suffered his first career loss at the hands of Hughes at UFC 50, but he has since avenged that defeat with two dominant showings against the same opponent, the last of which was so impressive that it set up a title rematch with Serra.

St Pierre is adamant that he was his own worst enemy when Serra knocked him out to snatch the title at UFC 69 in a huge upset.
