Liverpool need to sign a defender and another midfielder this summer to have a successful season.
That is the view of club legend and Sky Sports pundit Jamie Carragher, who spoke after his side's 2-1 win over Newcastle United.
While the Reds were successful with their smash and grab at St. James' Park, Carragher admits to having concerns about their squad depth and quality.
Speaking to Sky Sports, Carragher said: "Liverpool have been Manchester City's biggest rivals for the last four or five years, and Arsenal came to the fore last season. But why can't Liverpool be that team again this season?
"The squad that Liverpool have right now isn't good enough to challenge Manchester City, but they've got to go for it in the transfer market this week in terms of bringing in another defender and midfielder. That has to happen because Liverpool can still be the biggest rivals to Manchester City.
"They've made a decent start to the season, but when you've got someone like Alisson - a world-class goalkeeper, maybe the best goalkeeper in the world - Virgil van Dijk and Mo Salah, these are players who are not coming to the end of their careers but are at that stage where if Liverpool are going to go on to do something big again, it has to happen in the next year or two.
"So really go for it in the last week of the transfer window to get a squad that is good enough to challenge Manchester City."
