Former UFC welterweight champion Georges St-Pierre is set to make his return to the octagon after a four-year layoff when he challenges middleweight champion Michael Bisping at UFC 217 later this year. St-Pierre has made it clear that he is coming back to fighting to cement his legacy and is only interested in the biggest fights, so what happens if he beats Bisping? While St-Pierre would ostensibly be forced to defend his title against interim champion Robert Whittaker, that bout seems unlikely to have the kind of big fight appeal GSP is looking for.
