Kevin MacDonald expects Aston Villa's players to be the target of Premier League predators after failing to qualify for the Europa League group stage.
But he insisted no-one under contract would be leaving before the transfer window closes on Tuesday if they are still needed by the club.
Ashley Young has been consistently the target of speculation linking him with a move to Tottenham, who this week booked their place in the Champions League group stage for the first time.
Caretaker boss MacDonald said: "I am sure clubs will be interested in players because there are good players at Aston Villa. You'd expect not being in Europe to be a factor but you'd expect it from the clubs that are playing in Europe in that they might want an extra big player.
"We've not had anything (enquiries) as such. People would have told me if there were any enquiries. We've had nothing so far.
"But in terms of convincing players to stay, it might not be their choice. If the club needs them, and they are under contract, the club will probably want to keep them."
MacDonald, who will decide after tomorrow's game with Everton if he wants to apply for the job on a permanent basis, believes the squad may need strengthening after losses to Newcastle and Rapid Vienna. He said: "The results over the last two games suggest that."

Coyle critical of transfer window
Bolton boss Owen Coyle accepts the transfer window is now very much a part of English football -- but was a far bigger fan of the system that preceded it.
Five new players have arrived at the Reebok Stadium this summer but the manager had hoped to strengthen his squad further by bringing Arsenal midfielder Jack Wilshere back for another loan spell after his successful stint with Wanderers last season.
Neither that, nor a similar deal for Manchester United's Tom Cleverley, have materialised yet and it looks unlikely Bolton will be doing any more business before the summer window slams shut on Tuesday -- leaving Coyle questioning why trade is no longer unrestricted.
"I'm old-fashioned in many ways and I'm from the old school -- there really shouldn't be a transfer window," Coyle said. "I can understand why people brought it in, but for me, the old-fashioned system, where if you had two or three injuries you would go and buy a player if possible -- I don't see what is wrong with that."
