Lambert bolstered his defence on Wednesday with the capture of Middlesbrough left-back Joe Bennett - the fifth signing of the summer. But he is now looking to add firepower to supplement fit-again Darren Bent and the currently-injured Gabriel Agbonlahor.
Villa have increased their bid to sign Genk forward Christian Benteke to around ?5.5 million after their initial offer was rejected. The midlands club are hoping to hear on Thursday whether they have been finally successful in their attempt to land the Belgium international.
Benteke has made it clear he wants to fulfil his dream of playing in the Barclays Premier League although reports he had gone on strike were unfounded.
But Lambert is also looking long term and believed to be keen on Chesterfield's 21-year-old striker Jordan Bowery.
Bowery has two years remaining of his current contract.
He made his debut for Chesterfield four years ago and has made more than 80 appearances for the club.
Charlton midfielder Dale Stephens is also on Lambert's radar.
