Ospreys have signed Wales full-back Lee Byrne and utility back Tal Selley from Welsh rivals Llanelli Scarlets on three-year contracts.
Lee Byrne has established himself as an international full-back
Byrne, 25, made himself a fixture in Wales' Six Nations squad this year with a string of impressive performances.
The 6ft 2in full-back has won eight caps, while Selley, 26, plays at wing or centre and has one Wales cap.
Ospreys coach Lyn Jones said: "Lee has developed this season into a fully fledged international calibre player."
The arrival of the pair to the region is another sign of the Ospreys' intent, after former New Zealand scrum-half Justin Marshall and Neath fly-half tyro James Hook were both added to the squad last week.
It is something of a homecoming for both players as Byrne hails from Bridgend, although he has played his senior rugby at Stradey Park, while Selley is an alumnus of Swansea University.
"We are delighted that Lee has chosen to get on board with the Ospreys," Jones added.
"We have signed another top-quality international who originally hails from within the Ospreys region.
"He played a prominent role in the Six Nations with Wales and is a full-back of some considerable stature who will fit in well at the region."
Although Selley has struggled to hold down a starting place with the Scarlets this season, Ospreys manager Derwyn Jones is sure there is better to come.
"Tal is a player who hasn't figured regularly for the Scarlets this season but I am confident that we will see the best of him over the next few years," he said.
"He is a quality rugby player who has genuine pace and we are all looking forward to seeing him line up within what is already an exciting Ospreys back line."
