with "risky spending" but have pledged their commitment to
the club.
In an open letter to fans, main owner John Henry said: "We will never place this club in the precarious position we found it when we took over at Anfield."
Liverpool are without a win in three games in their worst start to a season for 50 years.
Henry said he was disappointed at their failure to bring in a new striker.
Liverpool manager Brendan Rodgers has admitted he would not have allowed Andy Carroll to join West Ham had he known he would be unable to strengthen his squad.
Rodgers let the England striker leave for Upton Park as he was convinced he would bring in either Fulham's Clint Dempsey or Chelsea's Daniel Sturridge on loan.
The Reds boss, who has the option of recalling Carroll from his season-long loan in January, insists he was not misled by the club's American owners, Fenway Sports Group, over transfers.
In the letter to fans published on the official club website, Henry said: "I am as disappointed as anyone connected with Liverpool Football Club that we were unable to add further to our strike force in this summer transfer window.
"But that was not through any lack of desire or effort on the part of all of those involved.
"They pushed hard in the final days of the transfer window on a number of forward targets and it is unfortunate that on this occasion we were unable to conclude acceptable deals to bring those targets in.
"But a summer window which brought in three young, but significantly talented starters in Joe Allen, Nuri Sahin and Fabio Borini as well as two exciting young potential stars of the future - Samed Yesil and Oussama Assaidi - could hardly be deemed a failure as we build for the future."
