Villa boss Steve Bruce says they'll "try to break the bank" for England Under-21 star Onomah.
The 20-year-old midfielder was the standout performer in Saturday's 2-1 win over Fulham.
And Bruce would love to turn his loan move from Tottenham into a permanent one.
“Josh Onomah was terrific," purred Bruce. “We'll try and break the bank for him!
“But we know Spurs have got a very good player there."
