The Blues manager reiterates his intention to lodge a fresh offer for the unsettled striker but is keen for further talks to wait until after the two sides face offJose Mourinho has confirmed that Chelsea will bid again for Manchester United striker Wayne Rooney, albeit after the two clubs meet at Old Trafford on Monday.
The Blues have seen two offers for the unsettled forward rejected by the Premier League champions, with manager David Moyes insisting that the England international is not for sale.
Goal exclusively revealed on Wednesday that United are planning on re-opening discussions with Chelsea as they look to include Juan Mata as part of any deal - but Mourinho insists that no talks will take place ahead of Monday.
"We did [bid for Rooney] before and we will do [again] later," the Portuguese told reporters after Chelsea's 2-1 win over Aston Villa.
"[But] I don't want Chelsea to do it before we go there ... from the ethical point of view."
On the night, Chelsea were pushed all the way by a revitalised Villans, with Antonio Luna's own goal and a late Branislav Ivanovic header maintaining their 100 per cent start to the Premier League season.
There were question marks over whether Ivanovic should have been given his marching order minutes before netting the winner after appearing to elbow Christian Benteke but Mourinho deemed the incident "50-50".
"That was very hard. I missed that about the Premier League!" he enthused. "Normally matches in the [Santiago] Bernabeu, we win every match very comfortable; this was very hard, it's what I like. I told Paul Lambert that they deserve a point, it wouldn't be unfair.
"Benteke makes a lot of fouls and the opponent who plays against him has to make a lot of fouls.
"Paul Lambert reminds me of me at his age. Now I complain with some decisions - at his age, I complained at every decision. Paul complains at every decision, I was the same. Benteke and Ivanovic, they are two giants, it was 50-50."
