Salah, who is the club's third-highest scorer of all time with 255 goals, revealed last month that this campaign would be his last with The Reds in what was an emotional goodbye to fans.
Reports have already linked the Premier League champions with several replacements for the Egyptian king including RB Leipzig’s Yan Diomande who could become a straight swap for the 33-year-old.
However, speaking to FruityKing, Waddle believes that Newcastle’s Anthony Gordon and West Ham’s Jarrod Bowen could be better options than Diomande as they offer Premier League experience.
“I think Jarrod Bowen is the closest I’ve seen to a player like Salah who gets the goals but he’s getting on a bit now. If West ham went down, there’s the possibility of Liverpool getting a couple of years out of him.
“Gordon plays on the left wing and I think he would prefer to be a left-sided player or a number nine now. He’s enjoyed playing up there for Newcastle United so I’m not sure about him taking Salah’s place at Liverpool.
“I’m sure he could play there and do it, I’m not saying he couldn’t, but he’s the sort of player who enjoys running into space down that left-hand side when it’s nice and open. I’ve seen many games where the other team have changed a player or changed the system because of how dangerous Anthony Gordon has looked down the left so why would you waste that?
“I’ve not seen a great deal of players who can score the amount of goals that Salah can. There are a lot of players who can create more chances and do some things better than Salah with the ball but I’ve not seen a player who could do exactly what Salah has done for Liverpool.”
Manager Arne Slot may be forced to break the bank for Salah's replacement as they chase down Diomande, Bowen, Gordon and even Bayern Munich’s Michael Olise who will take up the majority of the club’s transfer budget.
