Former Liverpool striker Michael Owen believes the team will find it tough to add to their attacking arsenal.
The Reds are in the market for a new striker, as they want to ease the load on their trio of Mohamed Salah, Sadio Mane and Roberto Firmino.
But Owen believes it will be tough for Jurgen Klopp to find the ideal striker in the transfer window this summer.
"It is so much easier if you're a scout or you're in the recruitment department of any other club bar the top six," he is quoted as saying by Goal.com.
"I mean, where do you go? How do you go and target someone, and they say 'am I going to start?' and you have to say 'no, Salah will start or Mane will start'?
"You can't go and get an absolute top player, unless they only have a couple of years left in their career. Or you go and buy the next young thing and maybe bleed him in for a year or so. To go and get someone in the guts of their career, at 24 or 25, that's so hard, and that's the only player that can really improve teams like this one.
"I know it's a dream for everyone [to sign world-class players] but it's so hard to improve your team if you are in the top six, unless you're not happy with one of your players and you look to replace them. But Liverpool have a great front three, and so if they're going to buy, it would more likely be one of the options I mentioned."
