Luke Wallace has signed a contract extension with Harlequins with boss John Kingston touting the flanker for future England honours.
The 26-year-old academy graduate's new terms come hot on the heels of Quins recruiting Montpellier fly-half Demetri Catrakilis for next season.
Back-rower Wallace has made 135 appearances for Quins since his debut in 2009.
Harlequins rugby director Kingston hailed Wallace's talents, admitting he remains nonplussed why the specialist openside remains uncapped by England.
"I am delighted that Luke has committed his foreseeable future to Harlequins," said Kingston.
"He is respected hugely in the group, both as a person and as a quality back row forward."
Wallace has represented England Saxons and featured in England's non-cap international against the Barbarians in May 2014.
England head coach Eddie Jones has insisted he currently has no natural openside flankers worthy of Test match action, ahead of the autumn internationals.
Injuries to James Haskell, Sam Jones and Mike Williams leave England's resources threadbare at openside however, leading to the suggestion Saracens lock Maro Itoje could fill the absent seven shirt.
Jones intends to select a "destructive defensive player" at openside rather than a traditional scavenger for England's autumn Test encounters.
Harlequins boss Kingston revealed his surprise that England continue to overlook Wallace, especially in light of their current injury profile.
"It is something of a mystery to me that he has not yet taken the step to the international squad to challenge for appearances on the highest stage," said Kingston.
"With the undoubted development, which still lies within him, I am sure it is only a matter of time."
Wallace however was simply keen to reveal his delight at securing his future.
"I'm really excited to have committed my future to a club, coaching set-up and squad that I truly believe in," said Wallace.
"My decision to renew was a quick and easy one. Harlequins is all I've known during my career and I can't imagine being anywhere else.
"I'm looking forward to working hard with an exciting group of players and positively impacting the history of Harlequins."
