Liverpool chairman Tom Werner says owners Fenway Sports Group have proved their mettle by spending big in the transfer market since their arrival.
The signing of Newcastle United left-back Jose Enrique for a fee in the region of £6million takes manager Kenny Dalglish's summer spending up to around £50million.
"I don't think anybody is working harder than we are right now to continue to see if we can recruit talent," Werner told the LFC-TV.
"We are willing to spend pounds to upgrade the team and I think that both clubs, both the Boston Red Sox and Liverpool, are blessed with management that is tireless and smart and I think that is the essential ingredient.
"It's been our goal to try to improve our position on the pitch, and to try to create a environment for players to say they want to play in Liverpool and bring some of the lustre that all the fans know back to the club."
