The Reds have not made any significant moves in the transfer window, much to the shock of supporters.
With Real Sociedad midfielder Martin Zubimendi rejecting a move, they are now in a position where new boss Arne Slot may only have last year’s squad at his disposal.
"Liverpool supporters are a little concerned with the lack of activity in the transfer market," Fowler wrote in a column for The Mirror.
"I understand where they are coming from.
"I would like to see new sporting director Richard Hughes add a holding midfielder, a center-back and a left-back to the squad before the window closes. There is still plenty of time to do some business but, ideally, you want to give news signings a few weeks to settle in."
