Southampton executive director Les Reed says the club have no intention of cashing in on Virgil van Dijk and Cedric Soares as they prepare for life under new manager Mauricio Pellegrino.
Centre-back Van Dijk was caught up in a transfer row over interest from Liverpool, while right-back Soares has been linked with Everton, Tottenham and Barcelona.
Reed, though, insists Southampton are not about to see more key men depart the club, as has been the case in years gone by when players including Adam Lallana, Victor Wanyama and Dejan Lovren have all left.
"None of those players are for sale. I can't make it any plainer than that and that's the way we mean to go forward,'' Reed told Sky Sports News. "We built this squad over some time and think we have a strong squad.
"We will fine-tune it but, other than that, we are looking forward to a very competitive season next year and we plan to go forward on that basis.
"There may be players that go on the basis it is the right thing for them and the club at that given time, but we don't expect that to be wholesale and this is simply doing sound business in the transfer window.''
Former Argentina defender Pellegrino was last week confirmed as successor to Claude Puel, who was sacked by Southampton at the end of the 2016-17 Premier League campaign.
Pellegrino led Alaves to the Copa del Rey final last season, and had previously coached under Rafa Benitez at both Liverpool and Inter Milan.
Pellegrino is set to join up with Southampton in time for the start of preseason training, with a friendly against Brentford pencilled in for July 22.
Reed expects Southampton to be proactive in the transfer mark as Pellegrino weighs up his options going forward.
West Brom have been linked with a £14 million deal for forward Jay Rodriguez, whose first-team chances were limited last season.
"We track players over years and when the new manager comes in like Mauricio, we take him through that process,'' Reed added. "He had done his homework on our squad and we don't believe we need to turn over players every year just to freshen things up.
"We've got a strong squad now and it would be about adding players bringing more value and power. It's not broken so there is no need to bring in players just because of fashion or to get people excited in the transfer market.''
