1. Big test for Ibargüen - Triple Jump
Caterine Ibargüen is on a mission to reclaim her Diamond Trophy this season, and she has already booked her place in the IAAF Diamond League Final with victories in Shanghai and Oslo. In Paris, though, the Colombian faces her toughest test yet in Paris as she goes up against both Olga Rypakova and Yulimar Rojas. Rojas pipped Ibargüen to gold at the IAAF World Championships in London last summer, before Rypakova stunned both of them by securing the Diamond Trophy in Zürich. While Ibargüen will be out to put both the pretenders in their place, Rojas and Rypakova will both be keen for a win - not just to show that they can still beat the Colombian, but also to pick up valuable points and move themselves into a qualifying spot.
2. Warholm vs Samba reloaded - 400m Hurdles
Having surged to fame and glory last season, Norwegian hurdler Karsten Warholm has been outshone by the man of the moment Abderrahman Samba so far this season, the Qatari breaking the Diamond League record on no less than three occasions. Despite remaining in Samba's shadow, Warholm has still broken his PB and has kept within a few strides of the Qatari on multiple occasions, as the two rising stars push each other to ever further heights. They do battle again in Paris, with Warholm needing just a few more points to bag his place in the Final.
3. Ortega and Shubenkov eye final spot - 110m Hurdles
In the other hurdling Diamond Discipline, Paris is set to welcome a host of superstars, as the likes of Orlando Ortega, Diamond Trophy holder Sergey Shubenkov and Aries Merritt descend on the French capital. For Shubenkov and Ortega, who are currently second and third in the standings, this is a chance to secure their place in the Final. The French crowd will also have the chance to cheer on some of their local heroes, as the likes of Darien Garfield and Pascal Martinot-Lagarde look to use the home advantage to get points on the board and break into the qualifying positions.
4. Ta Lou set to qualify - 200m
Right up until Dina Asher-Smith's fine win in Stockholm, 2018 had been the undisputed year of the Ivorians in the women's sprints, with Murielle Ahouré and Marie-Josée Ta Lou sharing the spoils between them in the 100m and 200m. In Paris, Ta Lou has the chance to continue her winning ways and book a place in the Final as she lines up against the likes of Shericka Jackson, Kyra Jefferson and Kimberlyn Duncan.
5. Duplantis in Lavillenie's back yard - Pole Vault
After winning a first Diamond League meeting and also beating Sam Kendricks for the first time in Stockholm, young Mondo Duplantis can be considered very much among the favourites for the Diamond Trophy in the men's pole vault. In Paris, though, he not only faces Kendricks, but also his childhood hero Renaud Lavillenie. With both men currently on eight points and looking to shoot up the rankings and secure a place in the Final. For Duplantis, too, this is the next big test: beat seven-time Diamond Trophy winner Lavillenie in his own back yard, and his place in the absolute elite will be beyond any reasonable doubt.
