Swansea's growing strength as a club offers them protection against potential approaches for manager Garry Monk, says chairman Huw Jenkins.
Monk expects to sign a new contract with the Swans "in the next few days".
"We've gone to a new level and that's a good protection policy," said Jenkins.
"Perhaps we could be exposed by the biggest clubs in the Premier League and perhaps by the biggest clubs in Europe.
"But in general we are a strong, successful club ourselves and perhaps that's the biggest protection of all in [terms of] some of the clubs that may be interested in our manager or players."
Swansea finished their season with a 1-0 loss away at Crystal Palace, but it was still the Welsh club's most successful season in the Premier League.
In Monk's first full campaign since succeeding Michael Laudrup as manager, the Swans claimed a club-record points tally of 56.
And Jenkins added: "The good thing where we are as a football club is we've got a really good, really strong squad of players."
