O’Neil has recently signed a new two-year extension to his contract with Boro.
“We’re aware of the availability of Gary O’Neil from Middlesbrough,” Allardyce said.
“But at the moment we don’t have any finances in place to move for any players.
“If that changes and the board tells me there is, then we’ll have a look in the market.
“If it doesn’t, then we stay with what we’ve got.”
