Sean Dyche insists that Burnley would have had to break their financial model to improve their chances of staying in the Premier League.
The Clarets head to Hull City this Saturday needing to win to keep alive their slender hopes of avoiding a return to the Championship.
But Dyche is adamant only the fine margins of top flight football have denied his group a better opportunity to going into the final three games looking up.
He said: “Two and a half years ago the club was coming out of having Premier League money. That brings some challenges.
“The Board felt they wanted to learn from that and move a different way. I made them aware this a really tough challenge to do it that way, by spending so little and having such a low wage bill.
“But I believe in the players and what we can achieve. I always have done, so I took the challenge on knowing it was going to be tough.
“It has proved to be tough, but the margins are so, so fine. We’ve been in pretty much every game and that’s been the real frustration.”

He added: “When you look at the resources available, I think myself, my staff and the players have given a lot to the cause.
“Outside help through finance, if there was finance available, would obviously have supported the group.
“But I did say early season - and I said again in the transfer window - that a couple of million here or there, at this level, doesn’t really affect you.
“Our challenge is to bring in players who are better than the ones we’ve got.
"Last season we went up with a record points’ total, with more points than the leaders this year, so they are a fair group of players.
“If you want to better them and you go back into that market in the Championship, trust me, those fees are massive.”
Burnley fans are reminded that tickets for Saturday’s game at Hull City are now sold out.
