Brendan Rodgers completed the £12m signing of Chelsea striker Daniel Sturridge almost a fortnight ago, with the England international scoring twice since moving to Anfield.
The Reds have been heavily linked with a last-minute move for wantaway Internazionale midfielder Wesley Sneijder, while Molde’s Vergen Forren is another named linked with a switch to Liverpool.
But Ayre insisted the 18-time English champions would not spend money for the sake of it this month, despite Rodgers’ desire to strengthen his squad.
“We may or may not add to that further before the end of January. That’s something we’re still working on and considering,” said Ayre.
“We will only buy when the right deal is there at the right time. We will continue to add to the group and improve it. Daniel Sturridge signed recently and has made an immediate impact.”
Ayre also believes that Rodgers is creating the perfect blend of youth and experience at the club, with the Liverpool chief vowing to keep their world-class players.
“Of course we have to progress to be able to hang on to our world class talent. But we wouldn’t be doing it if we didn’t think we would progress,” he added.
“You need to have a mix in your squad and we have probably got the best balance in terms of any team in the league.
“Our two most senior players have spent their whole careers at this football club. At the lower end we have a bunch of five or six very young players who have come through our Academy process and are now contributing for the first team.
“Then in the middle of that we’ve got world class international players like Luis Suarez, Daniel Agger, Martin Skrtel, Glen Johnson, Pepe Reina and Lucas Leiva. That’s the right mix I think.”
