England take on Ireland in the final warm-up for the two sides, but which five players are under the most pressure to perform?
Stuart Lancaster and Joe Schmidt have revealed their World Cup squads, and now have a chance to give their starting XV's chances to prove their worth at Twickenham.
With this the last game before the two teams launch their World Cup campaigns, there will be plenty of competition for starting places in both camps.
We take a look at five players with added pressure to put in a good 80 minutes on Saturday.
Billy Vunipola started last year's autumn internationals as the first-choice No 8 for England before a dip in form saw him replaced by Ben Morgan. Morgan then seemed set to feature in the Six Nations earlier in the year but a broken leg suffered in January sidelined him for the remainder of the season.
Though Morris backed Billy Vunipola to do well in the World Cup, he feels it's the right call to give Morgan game time.
"Give Ben Morgan a start against Ireland," said Morris. "Get him some game time, he needs that."
Morgan himself told Sky Sports he is happy with the progress he's made in his return from injury.
"I have a lot of training under my belt and I feel really confident with how I have gone," said Morgan. "Mentally that was a big one to get over so I was really pleased with how that happened.
"I am just looking to get back to the form I was in in the autumn. Like I said, the way we train has been pretty intense and physical so I have had plenty of tests."
In Ireland's World Cup squad the most intense battle for places was in the outside backs, personified by the omission of a player as talented as Andrew Trimble.
Simon Zebo made the cut in Joe Schmidt's 31, but despite featuring in the No 15 jersey just three times in 17 Ireland appearances, Schmidt has backed Zebo to play understudy to Rob Kearney; citing it as the reason Zebo was selected this week.
"We just felt it was important to get Simon a little bit more time at full-back once we decided he was going to cover full-back for us," said Schmidt.
"Rob Kearney has a bruise on his knee but he trained fully and we could have picked him."
Zebo played on the wing in four of Ireland's Six Nations matches this year, but was picked at full-back against Scotland in which he scored a try.
British and Irish Lion Parling returns to the England team after missing out against France in Paris, and comes in at a time when his primary role is under great scrutiny.
England's lineout failed to fire against the French and as a result hooker Tom Youngs was criticised, but Parling believes the blame should be shared and has vowed that he and his forward colleagues will prove they are still a formidable unit.
"We have beaten up teams and performed well in the past. You don't suddenly became a poor set piece side. I don't think so anyway," Parling said.
"I just think it is a few little fix-ups. It is never one area. It really does get to me when people always seem to blame the hooker. Sometimes that's out of order.
"There was one bad throw in the last game against France. No matter how many times I say it's not their fault they still get blamed. That's life.
"I don't think there's a big problem. It's a combination of little things that didn't go well, but I still think we're a very good set-piece team.
Going up against Parling in the lineout is Ireland's Toner.
Toner partnered Paul O'Connell in the last two Six Nations campaigns, both of which were won by Ireland. The partnership was a key feature of the success of the team, as they dominated the lineout.
However recently there has been the resurgence of Ulster's Iain Henderson, who has built on his reputation as a useful second rower in the Irish ranks.
Henderson featured in all five of Ireland's Six Nations matches this year from the bench, and started in both warm-up matches against Wales last month. In Ireland's loss at the Aviva Stadium last week Henderson scored a try in a superb all-round performance.
Toner is aware of the pressure he is under to nail down his starting spot, and will relish the chance to go up against Courtney Lawes and Geoff Parling to prove his worth to Schmidt.
Despite not featuring for England so far this year, Brad Barritt is likely to be England's first-choice inside centre throughout the World Cup.
A series of injuries has kept the Saracens midfielder out of international action but he is now ready for action.
Luther Burrell took over the No 12 duties during the Six Nations, but was omitted from the England squad as Sam Burgess and Henry Slade were preferred to the Northampton centre. Barritt has leapfrogged them both for a starting spot against Ireland, though this week he did praise the pair for their contribution to the team.
"They've impressed and they've pushed their inclusion," said Barritt.
"Credit must go to both of them for an incredible amount of hard work."
Coming up against a formidable pairing of Robbie Henshaw and Jared Payne will be an intense return for Barritt, but the South African-born No 12 won't shirk his duties when it comes to tackling or bringing the ball up for England.
