Billy Vunipola is determined to make sure he is one of the current crop of England players who manages to stay in Eddie Jones' plans for the 2023 World Cup.
Jones recently warned that he expected a turnover of players before the next tournament in France of up to 60%.
That message has hit home hard with 27-year-old England and Saracens number eight Vunipola, who is currently recovering from a fractured arm.
"Everyone needs to take heed of his messages and make sure you aren't the guy who gets cut," Vunipola told the Daily Mail.
Vunipola also has his sights on making the squad for the British and Irish Lions tour of South Africa next summer, having missed the trip to New Zealand in 2017 through injury.
"I need to play for England first, to put myself in the shop window to play for the Lions. I have to show I'm good enough. It's going to be massive and there's so much competition. It's definitely something I'm very keen on doing."
