Tim Sherwood has said that Liverpool are a "top goalkeeper" away from mounting a Premier League title challenge.
Reds manager Jurgen Klopp has used both Simon Mignolet and Loris Karius between the sticks this season, with the German recently saying that the latter is his first-choice stopper.
Sherwood, who has said that Liverpool are the closest team to challenging Manchester City for a top-flight crown, is confident that a new goalkeeper could give the Merseyside club a boost in their title hopes.
"Liverpool are the closest team to be challenging Manchester City," the former Tottenham Hotspur manager told Sky Sports News. "Yes they lost Philippe Coutinho, which was a big blow, but they've coped without him. They look they will need to find a replacement for Emre Can, he's a big player too, but they do have Naby Keita coming in the summer.
"Roma goalkeeper Alisson Becker is a good prospect. There's a lot of noise coming out of Liverpool. Perhaps he has a buy-out clause, otherwise they wouldn't be tracking him down as they reportedly are.
"The key for Liverpool's current goalkeepers in the mistakes they have made. Liverpool cannot gamble, they need a sure thing. It's a key position and you're not going to win anything without a top goalkeeper."
Liverpool are third in the table, having lost three games this term.
