Liverpool legend John Aldridge has taken aim at the club's owners, FSG.
Aldridge believes Fenway Sports Group need to loosen the purse strings.
“Gerard Houllier and Rafael Benitez were given big money to spend during their time as Liverpool managers, but Brendan Rodgers and now Klopp have been restricted for whatever reason by the structure now in place at the club," Aldridge told the Irish Independent.
“We all respect FSG for taking over the club and removing the hated owners that preceded them and appreciate that they don't have the huge finances to compare to the sugar daddy owners at Manchester City and Chelsea.
“Yet we have a right to expect a little more than we have got from a club seemingly reluctant to spend big money in the transfer market and prefer to run a very tight financial ship that is restricting progress for the team.
“In many ways, Klopp is doing a decent job to keep Liverpool in the mix with the Premier League's top four when you consider he has barely spent any money since he arrived at the club, but we want this team to kick on now after a top four finish last season."
