Ospreys coach Jonathan Humphreys has ruled out any new recruits arriving at the region ahead of next season due to no finances.
Kahn Fotuali'i is one of the names leaving the region at the end of the season, but Humphreys has ruled out any new signings due to the region's lack of funding.
"We would love to spend in the summer but there is no money," said Humphreys to BBC Sport.
"There is no money at all for us and that comes from factors like having the least funding of anybody.
"Therefore, there is no money left to go and strengthen."
"Of course it's frustrating, especially when you are judged on what you win and how you go in the major competitions and everybody in that competition has more money than you to strengthen their squad.
"Look at Glasgow, they have gone on a helluva run purely on the strength of their squad. It is huge.
"Leinster will be the same. Munster next year will have the ability to go and get more players. Everybody is going to get stronger."
Humphreys also believes that the positioning of the Six Nations within the season should be reviewed, with the Ospreys losing several of their key stars to Wales during important phases of the season.
"I cannot see it improving and that is a worry," added Humphreys.
"If it stays as the format (the season) that we fund international rugby players and some of them we get for less than 10 games a a season, even though we are paying their wages, I think it makes sense it is at the end of the season.
"We need these players playing for us and there is a huge amount of rugby played when these boys are away. It doesn't make sense."
