Alex McLeish must sell before he can buy, but believes he will not need to if certain individuals step up to the plate.
The Aston Villa boss feels that further additions will not be required if those already on the books at Villa Park prove their worth.
He is specifically referring to those who have drifted out of favour under his predecessors and appeared destined to be on their way out of the club at one stage.
The likes of Stephen Warnock and Stephen Ireland have, however, been given a second chance under McLeish and the Scot is hoping players who were drafted in for big money will make the most of the opportunity presented to them.
Ahead of Villa's opening fixture against Fulham on Saturday, McLeish said: "We have to trade again before we can bring anyone else in.
"But there were players, don't forget, who weren't involved last season like Warnock and Ireland.
"They have trained to a very good level pre-season and it is up to these guys to show they can do it when the real deal is about to start.
"I'm not going to guarantee anyone walking into the team or tell you who is going to be playing.
"But these two guys are players Aston Villa spent a lot of money on in terms of transfer fees and wages.
"We have to try and get more out of them and the signs have been good.
"The two of them have put in a great shift in pre-season and we know what they are capable of giving. The evidence is there.
"They both played for their countries. Ireland had a marvellous season with Man City two years ago and Warnock played for England."
