Jose Mourinho and Chelsea will wait until after Monday's Barclays Premier League match with Manchester United to make a third approach for transfer target Wayne Rooney.
Chelsea have seen two offers for Rooney rebuffed by United, who insist the England striker is not for sale.
Mourinho will test that resolve, but not until after the trip to Old Trafford.
"I don't want Chelsea to do it before we go there," said Mourinho, following Chelsea's 2-1 defeat of Aston Villa.
"Everybody in the club, in the board, they agree with me. They share that opinion.
"I think this period, by the ethical point of view, is a period where we're going to be quiet."
The transfer window closes on September 2, so Mourinho and Chelsea may bide their time over Rooney.
Mourinho has expressed sympathy with the view of managers who believe the transfer window should close before the start of the Premier League season.
Yet the self-styled Special One is still determined to do his utmost to recruit Rooney, who appears unhappy at United.
Ba started against Villa, with Lukaku coming off the bench and Torres not in the matchday squad.
Speaking prior to the Villa clash, Mourinho said: "We have plans B and C. Don't ask me names because it's difficult to speak about players from other clubs."
