One day after Warren Gatland unveiled his squad for the British and Irish Lions tour to New Zealand, Eddie Jones has revealed the 31-men who will play for England in Argentina this summer.
But there is no denying Solomona's talent, with the 23-year-old Auckland-born wing having scored 10 tries in 13 appearances for Sale since joining in December.
Rugby league convert Solomona, who qualifies for the RBS 6 Nations champions on residency grounds, and back row prospect Underhill feature in a 31-man party that is missing Danny Cipriani.
Jones insisted eligibility rule changes had played no part in Solomona's selection, saying: "We don't need to warehouse players in England".
"I think I am as desperate to coach England to a win as any England coach and I haven't been brought up in England, as you can tell by my accent". "It's about how you feel and how much you want it".
Solomona's cross-code move from current Super league leaders Castleford to Sale remains a matter of dispute between the two teams.
You have the Lions, those who have featured for England but miss out on this trip to Argentina and then the youngsters with huge futures. He's got that ability, when he gets the ball, to score a try.
On Exeter scrum-half Jack Maunder: "Maunder is an interesting player, a cheeky little b****r which is why I like him". "I think we'll keep them competing against each other". "Apart from that I want them to get on with it". He scores tries and that's their job, wingers.
"Wingers are like goalkeepers - a goalkeeper has so many saves to make in the game and the good goalkeeper makes those saves". But secondly, it gives him the chance to give nearly everyone with worldwide aspirations, old and new, the most monumental boot up the backside.
"[I want them] not to forget what they were good at, that's important", Jones said of his former rugby league players.
But if there is a risk of a double hangover after England's 18-match unbeaten run came to an end in Ireland last time out, the eager young pups billeted to join them for the first time should clear it.
Jones has tapped into the highly successful England Under-20 production line in picking the 15 debutants, but his senior players will form the core of the starting XV for the two Tests in San Juan and Santa Fe. "If players aren't like that they won't play for England". This is the ideal opportunity to bring young guys through. The talent there is just so exciting. The only thing the senior players ought to ask of them is to tone it down. Jones has also mixed up his coaching team so they are taking on new roles; everyone is being kept on their toes. Jones, though, is adamant no one should assume anything, his senior players included. And find them a steak restaurant at night.
There was a message, too, for the likes of Christian Wade, Marland Yarde, Teimana Harrison, Mike Williams and Tommy Taylor, who missed out on selection.
