Villa face paying up to £50million if they want to prise Brennan Johnson from Nottingham Forest.
The 22-year-old Wales international forward is on the club’s list of possible targets but will not be available on the cheap, with Forest having already rejected a £30m approach from Brentford.
Villa boss Unai Emery has made adding a wide forward or winger a priority of the summer window. Leicester’s Harvey Barnes remains under consideration and would be available at a lower fee though he, like Johnson, has several other Premier League admirers.
Athletic Bilbao winger Nico Williams is another player Villa have considered but the 22-year-old is expected to commit his future to the Basque club for at least another season by signing a new contract.
