"The one every club would like is Isak," he told the Overlap US. "I'm not sure we're in a position where there's absolutely great centre forwards around that you can take your pick.
"Do I think Liverpool can buy Isak? I don't know. I'm not sure Liverpool would want to pay that type of money for that player, it's not their model, their model is 'we'll get the next Isak'.
"They'll be probably kicking themselves thinking. 'why didn't we get Isak from Real Sociedad?' I don't think they'll go break the bank for him.”
Carragher then targeted Eintracht Frankfurt striker Hugo Ekitike who has been linked to the likes of Arsenal and Manchester United ahead of the summer transfer window. He believes he would be a perfect fit for the Reds as he is younger and fits their transfer strategy perfectly.
"There's the lad at Eintracht Frankfurt who scored against Tottenham, that smacks to me the type of player Liverpool would sign.
"He's 22, he's at a club who'd be a selling club, done very well there, went to PSG as a very young boy after lighting up the French league but it didn't quite work out for him.
"He's got great numbers and the type of player that Liverpool would sign rather than maybe going for an Isak."
Both striker look set to move this summer as several top sides attempt to lockdown their signatures. With Liverpool set to win the Premier League they may have more pull than clubs such as United but only the future will tell if the Red Devils and Arsenal find success in Europe which could shake up the transfer market.
