Aston Villa boss Martin O'Neill says Liverpool know what they have to pay to land Gareth Barry.
"Liverpool have come back to us and we have responded to their proposal with a letter,'' O'Neill said. "We're still waiting to hear back from Liverpool after putting that proposal to them.
"It's really up to Liverpool. I really don't know how it's going to work out at the moment.
"I'm sure there will be some sort of resolution at some stage or another."
