Ospreys chief Andrew Hore admits they may find it hard to keep hold of some of their British and Irish Lions stars.
The Welsh region provided five players to the tourists as they
beat Australia 2-1 in a thrilling Test series.
Prop Adam Jones
and locks Alun Wyn Jones and Ian Evans have a year left on their Ospreys contracts.
"Yes, we've got challenges with three Lions coming up [to the end of their deals] at the end of the year and we'll be working hard on them," Hore said.
Hore has highlighted that top Welsh stars are already the beneficiaries from combined incomes from the regions, Wales and the Lions and a joint strategy involving the Welsh Rugby Union and Regional Rugby Wales is needed via the Professional Regional Game.
The Ospreys' other two 2013 Lions, hooker Richard Hibbard and flanker Justin Tipuric, are under longer-term deals.

Ospreys chief executive
“We've got to work collaboratively with the Welsh Rugby Union to ensure that we can do as much as we can to keep talent here”
"So Hibs [Hibbard] will be here and obviously Tips [Tipuric] which is fantastic, and the other boys are here this year," added chief executive Hore.
Alun Wyn Jones captained the Lions in the final, series-clinching Test in Sydney after Welsh compatriot Sam Warburton was ruled out through injury.
Both he and prop Adam Jones played in all three Tests, while Evans was a powerhouse in the midweek side and unfortunate not to force his way into Test reckoning.
The Welsh Rugby Union has
earmarked an extra £1m
to be distributed among the four regions - Ospreys, Cardiff Blues, Newport Gwent Dragons and Scarlets - this season.
However, there remains ongoing concerns in Wales at the numbers of top level players who have left for richer French and English clubs.
But Hore admits that it could cost Ospreys up to £1m in wages a season just to re-secure those three Lions stars who are out of contract next summer.
"Potentially yes, without a doubt and that's where we are extremely grateful that there's been a million this year but we've got to keep it in context," Hore added.
"It's really difficult because all of a sudden market forces come into play and these young guys who have been bubbling away quite nicely accelerate in cost.
"We've got to work collaboratively with the Union to ensure that we can do as much as we can to keep talent here, but I don't think we're always going to be able to keep talent here.
"I think we need to understand that the Celtic nations and Italy are probably in a similar boat to the southern hemisphere nations, which is why I feel we need to form a stronger alliance with the south because we need that global season, we probably need that global television revenue that it would generate.
"It'll be interesting over the next 18 months to two years to see what happens.
"Like any business that's just life and we're in a very lucky position that we've got some good young people coming through."
At least for the coming season Hore is content with how the squad is shaping up, with their established players augmented by some new signings and home-grown talent rising though the ranks.
"We're delighted with what we've done with the squad over the summer: we've kept a strong pack, we've re-signed 15 players last year," Hore said.
