Speaking to The i Paper, the former Liverpool striker said: "It’s a difficult one because as a supporter, you want them to sign every player under the sun!. If you’re not signing players, you risk potentially going backwards. Maybe [Darwin] Nunez will be a name on a few teams’ lists because he hasn’t played the amount of games he’d want to, so you assume Liverpool will try to bring a No 9.
"The problem is clubs know that they are potentially on the lookout for a No 9, so the prices will become silly. If you look at [Alexander] Isak, he’s going to be £100m plus easily. He’s a wonderful player, but Liverpool may not want to pay that, and they’ll look around. You could look at Ollie Watkins. He doesn’t really fit the model in terms of what Liverpool want, given his age [29 years old], but I’d go and get him for a couple of years because he’s a tremendous player and established and experienced in the Premier League."
