Rugby Union Weekly presenter and ex-England wing Chris Ashton has picked out his five 'definites' for his Lions XV to face the Springboks this summer.
1&2. Sam Underhill & Tom Curry (England)
"There is no debate with either Tom Curry or Sam Underhill. You're going to South Africa, you need tacklers. These two have proven that they are the best tacklers and poachers in the business. They are going to be essential playing against South Africa."
3.Finn Russell (Scotland)
"We've seen how good Finn is behind a good pack. I'm definitely going for him to start for the Lions in this situation."
JOIN THE RUCK:
4.Jonny May (England)
"May is a straightforward choice; you can't argue with that. Jonny is doing what he's doing being an outstanding winger."
5.Jonathan Davies (Wales)
"Davies is a veteran of two tours. Finn Russell picking off Jonathan Davies on the gainline, that's a tantalising prospect."
