We take a look at those players whose World Cup participation is currently in the balance so will be desperate to impress over the next few weeks…
The All Blacks full back has looked some way off his best of late and will face stiff competition from Nehe Milner-Skudder and Colin Slade as the back ups to Ben Smith.
Ashton’s recall to the England squad will have been a huge boost for the winger, however he still has some serious work to do if he’s to play his way back into World Cup contention.
The versatility of Beale could be a major strength in his case for inclusion, however he’s going to have to show some great form if he’s to break into the Wallabies starting XV.
12.Jean de Villiers
A year ago de Villiers was an automatic selection for the Springboks, but after missing the whole season he faces a race against time to prove his fitness.
The Welsh winger has come in for some serious criticism over the past 12 months and will have to work hard to prove he can still be a key contributor ahead of the World Cup.
Having battled his was back into the England squad, Cipriani now faces a major battle to try and prove that he adds enough value to the squad to justify World Cup inclusion.
With Rhys Webb taking over the starting role and a number of others snapping at his heels, Phillips will have to work hard to keep his place on the bench.
Despite being one of France’s best loose forwards, Picamoles will have a fight on his hand to prove his value to the French coaching staff.
It’s looking increasingly likely that Pocock could feature on the other side of the scrum to Michael Hooper, however he still has a fight on his hands to break into the starting XV despite his form.
After yet more injury setbacks, Croft looks a serious doubt for making England’s World Cup squad unless he can prove his value in the coming months.
The Wallabies lock has been another to come in for some major criticism, especially after a dire season with the Reds, so now has a real point to prove.
Having only had limited international exposure of late, the England lock may have to show more than line out nous in order to justify his selection.
3.Jannie du Plessis
With the Stormers front row dominating in Super Rugby this season, du Plessis will find it increasingly difficult to hold on to his starting shirt.
Welsh hooked Hibbard has been in and out of favour of late with Warren Gatland so will need to demonstrate some consistency to start.
After another rough year with injuries, Corbisiero faces a real fight to justify his selection ahead of the likes of Joe Marler and Mako Vunipola.
Which player do you think has the most to prove ahead of the World Cup?
